WIX MSI Installed from Windows Service - wix

Question

I am working on self installing software. There is a windows service that is running and can be notified that there is a software update. At that time, it will download my burn exe and do a process.start to silently install it. The installer works as expected except for one issue - the services it installs won't start due to a logon failure. If I change the service password in services, the service will start, so I am confident the issue resolves around the service account password. Here's the rub - if I run the exact same installer on the exact same machine from the interactive desktop (logged on user), it works!
Here is one of the services I install:
<ServiceInstall
Id="DataAcquisitionInstaller"
Type="ownProcess"
Name="DataAcquisitionService"
DisplayName="Data Acquisition Service"
Description="Handles all data acquisitions"
Start="demand"
Account="[SERVICEACCOUNTUSERID]"
Password="[SERVICEACCOUNTPASSWORD]"
ErrorControl="normal"
>
<util:PermissionEx
User="[SERVICEACCOUNTUSERID]"
GenericAll="yes"
ServiceChangeConfig="yes"
ServiceEnumerateDependents="yes"
ChangePermission="yes"
ServiceInterrogate="yes"
ServicePauseContinue="yes"
ServiceQueryConfig="yes"
ServiceQueryStatus="yes"
ServiceStart="yes"
ServiceStop="yes" />
<ServiceConfig DelayedAutoStart="yes" OnInstall="yes" OnReinstall="yes"/>
</ServiceInstall>
I have verified in the log that SERVICEACCOUNTUSERID and SERVICEACCOUNTPASSWORD are correct. The only difference I can see in the log is this:
When installing from service:
MSI (s) (30:80) [10:05:28:905]: Executing op:
ServiceInstall(Name=DataAcquisitionService,DisplayName=Data
Acquisition Service,ImagePath="C:\Program Files
(x86)\xxx\xxx\Services\DataAcquisitionService.exe",ServiceType=16,StartType=3,ErrorControl=1,,Dependencies=[~][~],TagId=0,StartName=.\test,Password=**********,Description=Handles
all data acquisitions,SecurityDescriptor=BinaryData,)
When installing from the interactive desktop as the logged in user
MSI (s) (44:E8) [09:45:57:518]: Executing op:
ServiceInstall(Name=DataAcquisitionService,DisplayName=Data
Acquisition Service,ImagePath="C:\Program Files

all data acquisitions,,)
What does this mean --> "SecurityDescriptor=BinaryData"? Is that what is causing my issue and if so, how can I fix it?
Thanks.
