Same selenium code runs differently on differents computers - selenium

So basically I split products from the same website into 2 groups between 2 laptops... And sent my code to a back-up laptop...
So here are 2 things that surprised me...
One laptop brings up a mistake (such as selenium.common.exceptions.ElementClickInterceptedException: Message: element click intercepted: Element ... is not clickable at point (470, 370)) every 3-4 products. But the other computer has not produced one single mistake for the last 40 products. How is that possible? It is the same code, the same web-site, the same internet connection...
While I was thinking about it, I just realised that the back-up laptop where I sent the code to, I did not use it for scraping before. I did pip installed all the libraries at the start, but I totally forgor to get chromedriver. The line in my code:
PATH = 'C:\Program Files (x86)\chromedriver.exe'
driver = webdriver.Chrome(PATH)
It was written on the laptop that produces errors evey 3-4 products now, and the one that runs perfectly has no chromdriver at the path provided.... So how is that possible? I do not get it?? How does it even run a browser?

That migth be because of:
different chrome-version ==> check version
different chromedriver-version ==> check version
different device metrics (javascript and headers) which the website detects and handles differently. ===> possibly use Selenium-Profiles for consistency.

Compiled Access Program Runs Fine on 7 Computers but Crashes on 3 others

I have written a rather complex application in Microsoft Access. It is split into front end and back end files. To protect my code, I have compiled it and saved it as a runtime .accde file, which I then changed to an .accdr file to ensure it operated as a runtime. I have created two versions of the application: one for those with 32-bit Office installed and one for those with 64-bit office. I have used Inno Setup to package the application, the data file, and other files such as the icon file, the license file, etc., into an installable package, which works just fine.
Among my team of 27 beta testers of this application, so far 6 have downloaded it, and I have tested it on four of my own computers. On seven of these computers, the installation works perfectly and the application runs with no problems.
On the computers of three of my testers, when they try to run it, they get this error message:
The expression On Open you entered as the event property setting produced the following error: Bad file name or number.
* The expression may not result in the name of a macro, the name of a user-defined function, or [Event Procedure].
I'm pretty sure I know where the code is that's causing the problem, but cannot for the life of me figure out why the application crashes on those 2 computers but not on others.
The On Open event I suspect of causing the problem checks the linked tables, gets their connect string, then looks at the path for that string for the back end database. If it does not find it there, the procedure pops up a file selector dialog and instructs the user to find the data file, then it relinks all the tables.
If anyone could point me in the right direction to fixing this problem, I would be extremely grateful.
This is typically caused by a reference labelled as MISSING.
You have two (three) options:
Run the application on the offending machines with a full version of Access that lets you debug the code
Create a small test application that lists and verifies the references you use, and run this on the offending machines
Remove those two customers
Thanks to all the contributors here. Because of these folks and additional online research, the latest answer I can find is this:
This error occurs on a small percentage of computers on which the app is installed, and no one has yet figured out why, what causes it, or how to fix it. The workaround is to install the 2013 version of the Access runtime, as later versions will still cause the problem.
At least one of the offending computers is running the Click-to-Run version of Office. Still gathering information, but that's the status as of now.

Uipath automation using RDP for community edition execution

While implementing solution for Level 3 Advanced Training on a separate machine, connected via RDP, i had to use the default UiPath Academy Recorder in order to upload my solution.
Here is the tricky part, although the automation completed successfully without the Academy Recorder on, while it was activated it failed (at random iterations) to recognize the download pop-up window element using the on-element appear activity. If the Academy Recorder was launched from the main machine the automation was also completed without errors.
Additional actions tried:
Check if element vanished
Check with On element exist instead
Also used wait for active and wait for visible options
Checked options for Interactive and Completed as well
-Is this related to the fact that the Academy Recorder slows down remote machine?
Thank you in advance,
Konstantinos
I'm quite aware this hasn't been answered in 2+ years (so hopefully you've solved it!)
An alternative way is to use the Wait For Download Activity.
This activity will wait for the file to be completely downloaded before moving to the next step (so be aware of any timeouts if a bigger file)
The activity is included with the UiPath.System.Activities

Selenium find element by name

I have made a number of tests. I’m getting some strange behaviour when running inspect on a different machine. I run inspect on my local machine and I can find an element by its name however on the test machine it can’t find that element’s name when using inspect.
The first image is from my local machine where it can find the element.
The second one is the test machine which can't. They both have the same version of Office so I'm not sure why this would be happening. It's like it isn't treating it as an element

Chrome OS bug - file select dialog (for uploads) 'stuck'

The best way to sum up the issue would be with a screenshot, but unfortunately my screenshots auto-save to downloads and so I can't upload them. What's happening is that when I enter the 'file select' dialog in trying to upload a file, it's automatically in the 'drive' folder and won't move to any other folder. I've tried restarting and resetting my machine, tried the upload process on a bunch of different platforms, tried using the other user account on my machine, tried updating my software, but none of these have made any difference. I can get into my downloads folder and open files from it fine outside of this context, and I can workaround by using the drag-and-drop to upload on platforms which have this feature, but otherwise I'm stuck.
I've googled extensively to see if anyone else is having this issue and have found this thread: https://productforums.google.com/forum/#!topic/chromebook-central/d7g9EEDsr8w but there's no helpful solution there (recommended a powerwash but the asker has already done this several times). I've also tried to find a solution with the help of my (programmer) employer, but no luck so he recommended asking here. It seems like it wouldn't be a hardware issue when I can still access the folder outside of this specific function, but if it were a problem with the running system it seems it would be happening across the board and therefore show up more in a google? If anyone has any suggestions I'd be very grateful as it's getting quite tiresome having to drag and drop things into Facebook messages to get them uploaded! The machine is less than a year old so if I can't find any solution I'll see about getting it replaced under warranty. Thanks in advance for any help, and please let me know if there's any key info I've left out!

Possible issue with running selenium tests on one machine concurrently

I have multiple similar sites (same layout, just different data), and each of them has drop down menu on mouse over (and disappears on mouse out).
I am using Selenium 2 and WebDriver, and I have one selenium test case that basically do the mouse over and make sure each of the link in the drop down menu works.
I am using selenium grid, so I have a hub and few test machines.
Because I have many sites (few hundred) to test, so I am thinking of making each machine to run the test case against multiple sites in parallel.
My concern is because there can be only one active browser at a time, will it cause issue if web driver tries to perform Action.moveToElement() on multiple browsers at roughly the same time? Will only the active browser performs Action.moveToElement() properly and other browsers fail? If there will be an issue, is there any workaround?
I have tried it using JUnitCore.runClasses(ParallelComputer.classes(), SomeClass1.class, SomeClass2.class, SomeClass3.class);, it decreased the passed tests percentage from 100% to about 67% when running three tests on a machine. Not good =/.
The good part - firefox actually can do it in parallel. If the FF instances are delayed between each other so they don't do the same thing at the same time, it works better. Some of the failures happened during a Firefox bootup - so if you can minimize closing and opening windows, do it. But still, sometimes it just fails for no reason.
If you really would use the saved time, then go for it, log all failed tests and run them again after the first round - this time one at a time.
You could also solve this, depending on your ultimate goal of testing, by not using the Action class with the mouse-movement click, but instead use the WebDriver findBy-click method or Javascript executor method. It would probably be less contentious when running multiple windows at the same time. If the Action class, when defining a mouse movement, uses native calls at all, such as "move to Point", then one browser over the top of another, then I would guess it's possible that the movement point could be masked by another window. I am really not sure about this, just giving you another idea to try.
