I'm getting the following error when trying to create a patch build:
Building package: D:\Build-Output\patches\testing\<blank>.msp
Running MSI patch compatibility tests... done.
Creating PCP database... done.
Creating MSP... error.
Exception - Reason: MsiMsp.exe failed to create the patch file.
Build finished because an error was encountered.
Not very helpful, I know. However, if I log in using a different account on the same computer, it works. My normal account is an administrator on the machine, but not a domain admin. The account that works is a domain admin. We tried promoting my account to a domain admin briefly, but that didn't work. We deleted my profile on the machine, and that still didn't work (account was still a domain admin). Any suggestions? I assume there's some permissions problem somewhere that we're missing, but my network administrator swears they had the same rights.
