Failed to execute view: 'Patch'

When I was using msimsp to create the msp file, after comparing all the files, and then preparing to build the patch, this error would occur:
INFO Comparing bytes...
ERROR: Failed to execute view: 'Patch'
ERROR: The Last Error Received is: 0x65b (1627)
ERROR: The Last Error Received is: 1: 2210 2: \\?\E:\msiUpdate\temp\SampleTarget.MSI 3: 1
INFO: Temporary folder is about to be cleaned out and deleted: E:\msiUpdate\temp
ERROR: Internal PatchWiz Error occurred.
ERROR: The Last Error Received is: 0x91 (145)
ERROR: During cleanup, could not delete the temporary folder: E:\msiUpdate\temp.
ERROR: The Last Error Received is: 0x91 (145)
I don't know which direction I should start investigating from.

Re: Failed to execute view: 'Patch'

Hello and welcome to our forums,

I'm afraid I can't say for sure why that is happening.

Are you using Advanced Installer to build the patch file?

Note that creating patches is a bit more strict compared to creating a major upgrade. A set of rules must be respected so that everything works as expected.

Creating Patches

Please have a look over the above article for mor information on this.

Best regards,
