First off, I do most my programming as tools for myself and know just enough to get by. I wrote a VB program which uses a vender's API DLL to communicate with a serial port device. I used VS Express. Works great on my Win 7 32-bit machine.
I handed my program off to a co-worker (didn't expect to share my tools) who has a XP 32-bit machine. I get a windows error that it "is not a valid win32 application" I made sure to include the vender's DLL with my executable.
I really don't want to have to install VS Express on his computer as that is how I have solved the issue in the past. I could use some pointers on cross-platform compatibility. Not looking to make my software universal, just to get it running on a XP machine.
Thank you,
Xp only supports up to .NET framework 2.0 if you want to use it on all versions of xp.
So you need to check with version he has or you want to support.
So if you want it to run on Xp "All versions" you need to make it .NET framework 2.0
Is .NET 4.0 Compatible with Windows XP SP2 or below?

Im developing continually an inventor Addin in VB.Net in visual studio 2019 ,
i have multiple machine different builds , but once in a while some machine just don't want to load the Addin f.e. the current version i have now works on all machines except one AMD machine .
When i compile the same project with the same settings no changes at all on the AMD machine with ANY CPU build option it runs without problem . When i do it on my primary developing machine it does not work on this other computer.
I checked dependencies with dependency walker , i do not get any error messages .
When i make breakpoints in DEBUG mode and debug dll compilation in the first methods called in the "StandardAddInServer.vb" file it does not reach it on the AMD machine when it is compiled on the Intel machine. But in reverse it runs smoothly .
I have no idea what this could be and I'm only speculating that is has to do with AMD/Intel difference of the machines . Any help would be appreciated to come to a solution.
Inventor 2018.3.7 Professional Build 287 is on the Intel i7-4771 machine Visual Studio Community 2019 16.3.9 , .NET 4.8.03761
Inventor 2018 Professional build 112 is on the AMD Ryzen 7 3700X machine Visual Studio Community 2019 16.7.2 .NET 4.8.03752
Any more information which could be helpful will be provided gladly .
Well.... i tought lets make the maschines identical in regards to software .. i started installing inventor updates one by one at Version 2018.3.1 the Addin magically was working .... so i hope i help somebody if the , addin automatically unloads without any error , its probably autodesk inventors fault ...
Are you using ANY CPU ,or are you forcing the project to a given bit size?
If you don't set this, and leave it at ANY CPU? Well, if you launch the application from Visual Studio (such as installing on that target machine), then the application will run as x32 bits.
HOWEVER if you launch the program from the windows command line (command prompt).
Well, if you use the x64 bit command prompt, you get a x64 bit running - in-process program. If any of your external .dll's or libraryes are x32 (or not compiled with ANY cpu), or you using any un-manage code libraies (say like ghostscript or some such)? Then your program will run (or try to) as x64 bits.
However, if you launch a x32 bit windows command prompt (there are two of them - one is x32, and one is x64). So, if you launch the .net exe (your program) from a windows x32 bit prompt, then your program will run in-process as x32 bits.
So, be careful here. Using ANY CPU from Visual Studio will ALWAYS get you a x32 bit program - including debugging. But RUNNING the program (launching outside of VS) will not always be x32 bits.
And the above behaviours seems to explain your issues/problems on the AMD machine. It was NOT that you installed VS on that machine, but that using VS to launch your program in fact FORCED it to run as x32 bits.
Bottom line:
do NOT use ANY CPU unless that is exactly what you need, and that you are VERY sure any external libraries are also compiled as ANY CPU, or in fact that any external libraries doe NOT USE any un-managed code.
All in all? I would config your project to force run as x86 ALWAYS, and thus you not get some surprises of code not working.
I doubt very much that the AMD CPU is the issue, and installing VS only worked because of forcing your project to run as x32 as opposed to x64 bits. It has zero to do with AMD here.
You could try with a former framework version like 4.6.2. That should fix the problem. It could be that the newer service packs of Inventor can deal with addins created with newer .net versions. When 2018 Inventor was released, .net 4.8 was not available.
Was Albert wrote is true as well. If the architecture of your dll doesn't meet that of your host process, it can't be loaded. A 64bit process can use 64bit dlls only whereas a 32bit one can deal with 32bit dll only. A .Net project won't be compiled by Studio into fully functional machine code (nowadays you can do this as well), but intermediate code only, which will be compiled finally by the .net framework on the target machine. If anyCPU is selected, you don't have to provide different versions for different hardware because of this behaviour.
I'm developing an application for a friend. I use Visual Basic 2012 (64-bit) and Windows 7 (64-bit).
I took a demo down to him to try it out to see what more features he wanted, and it was running ok.
When I got back the next week after implementing the new features, it refused to run on any of his Windows XP (32-bit) machines.
Error code:
MyApplicationName.exe is not a valid Win32 application
I tried it at a computer running Windows 7 (32-bit) which still worked all fine.
So, any ideas why it suddenly stopped running?
VS2012 will not generate an EXE that can run on XP when you use the default project settings. What matters is the .NET Framework version you target. If that's version 4.5 then there are two problems.
First one is that .NET 4.5 is not available for XP. Second one is important for this exception message, the compiler will mark the version of Windows that's required to run the EXE in the file header. That version number has always been set to 4.00. Until VS2012, it is now set to 6.00, the version number of Vista. XP will instantly reject your EXE with the "is not a valid Win32 application" message, even before it will tell you that it doesn't have .NET 4.5 installed.
Fix your problem by targeting .NET 4.0 or earlier. Project + Properties, Application tab, Target framework setting.
Try using corflags with /32bit+ and see if it works.

We have built an app with Visual Studio 2012 and it runs beautifully on any Windows 7 or Vista machine, 32 or 64 bit. However, when I try to run the app on an Win XP machine, I get this:
**
Prerequisite check for system component Microsoft .NET Framework 4.5
(x86 and x64) failed with the following error message:
"Installation of the Microsoft .NET Framework 4.5 is not supported on
this operating system. Contact your application vendor."
**
And then of course, when I try to install .NET 4.5 on the Win XP machine, I find out it's not supported.
At this point, I'm just wanting to know what can be done to get this app to run on Win XP. It's a calculator application written in visual basic.
Thanks Guys!
.Net framework 4.5 is not supported in Windows XP. If you're not using any .Net 4.5 features you can rebuild your app using .Net Framework 4 (In the Project properties).
I always hate these kind of answers, but a quick google search indicates that you can't get .net 4.5 to run on Windows XP.
IF you really really need your application to run, you can always use earlier versions of the framework
you can do this by
Right click on your project and go to
properties
application
target framework
and change that to something elxe
Is there a way to compile a VB6 component into 64 bits?
My feeling is that the answer is "no", but I would like to confirm this.
Please, if you can, paste a link to an authorative source that would confirm.
No. I hope this counts as authoritative.
64-Bit Windows
Visual Basic 6.0
runtime files are 32-bit. These files
ship in 64-bit Windows Operating
Systems referenced in the table below.
32-bit VB6 applications and components
are supported in the WOW emulation
environment only. 32-bit components
must also be hosted in 32-bit
application processes.
The Visual Basic 6.0 IDE has never
been offered in a native 64-bit
version, nor has the 32-bit IDE been
supported on 64-bit Windows. VB6
development on 64-bit Windows is not
and will not be supported.
No it cannot (well Microsoft has not released a compiler to compile it for a 64-bit environment), but this does not mean that it won't run on a 64-bit system. To run it in conjunction with IIS, you'll need to install the 32-bit version of IIS.
Does a 64-bit CruiseControl.NET exist or do I need to install the 32-bit version? Our CI server is Server2003 64-bit. Currently I have been testing on WinXP Pro and no problems.
If I do need to run cc.net 32-bit on a 64-bit OS, what issues should I expect to encounter? This post mentions a couple, Running 32-bit ASP.NEt 3.5 apps in Windows 2003 64-bit . I would also need to have the .NET 2.0 and 3.5 framework installed. Do I install the 32-bit versions if running cc.net 32-bit? Can 32-bit and 64-bit coexist on the same server?
A quick peek at the source code reveals that CruiseControl.NET is compiled with "Any CPU" platform, so it will (and does) run on either a 32 or 64 bit runtime.
My notebook runs 64 bit O/S and has no problems with CruiseControl.NET server or web dashboard (IIS 7). Just install it as per normal and you should be fine.
Personally I'd be really worried if it needed > 3GB of memory :)
It shouldn't be anything you need to worry about. Cruise control just launches the build, subsequent steps such as compilation can be 64-bit.
I don't think there's much benefit from making CruiseControl 64-bit at the moment. I'm running CruiseControl without issues on a 64-bit machine. The setup was not much different, other than the folder which it was installed into (Program files (x86)).
Generally speaking, all 32bit applications will work on a 64bit OS. I have been doing this with my webapps for some time. You will encounter issues only if you are trying to reference assemblies across the bit boundary, ie. 64bit assembly from 32bit application.
You should be already to run CC on 32bit mode on 64bit OS.
There are no seperate version of CruiseControl for 64-bit. But but you may run into an ASP.NET error if working with Win. Server 2008 and IIS7.
Workaround:
"C:\Windows\Microsoft.NET\Framework64\v2.0.50727\aspnet_regiis.exe" -i
and
"C:\Windows\Microsoft.NET\Framework64\v2.0.50727\aspnet_regiis.exe" -i "W3SVC/1/ROOT/ccnet"
NOTE: it is using Framework64 as this would not work for 32-bit.
