Hi
I apologize if this is the wrong sub-forum. We use VMware 5.1 , with vCenter to test our software application. We are in in the process of releasing a patch which is delivered via an MSP file.
Scenario 1:
- Obtain test build of the MSP Windows Installer Patch File
- Restore VM to "our" clean state snapsshot
- Install our main application.
- Install our patch
- Test...
All ok - Pass
Scenario 2 (designed to speed up testing)
Pre-setup (one time):
- Restore VM to "our" clean state snapshot
- Install our main application.
- Take second snapshot
For each patch:
- Obtain test build of the MSP Windows Installer Patch File
- Restore second snapshot
- Install our patch - FAIL due to Windows Installer sequencing error
The actual error is
MSI (c) (14:44) [13:36:45:194]: APPCOMPAT: looking for appcompat database entry with ProductCode '{4EC8B526-FBAA-4085-9D34-1B6E7A664C1C}'.
MSI (c) (14:44) [13:36:45:194]: APPCOMPAT: no matching ProductCode found in database.
Our main product is installed. If you search the registry for the ProductCode GUID, It is there. If I remove the main application, reinstall and then try to run the patch again, it still won't work. If I jump back to the original snapshot, it works, but won't after the snapshot restore with the main app already installed.
Does this sound like some sort of disk corruption?
Hopefully I was clear about what I am seeing.
Cheers
Tom
