Hi all, I'm attempting to upgrade to Pro 2.3.3 but every time I do I get a "Microsoft Installer failed to Run. Fatal Error during Installation". The logs show a "ERROR MSIInstallProduct failed: error code = 1603". I've never had any issue installing before.
I've went through some steps trying to clear this error
- Followed this guide
- cleared temp files there is now nothing in it
- ensured no locks existed (did a reboot then tried an install)
- it's not permissions as I'm running as admin
Before I completely uninstall 2.3.2, I just wanted to see if any one has experienced this and how they went about solving it.
