Hello,
I am having an issue updating exchange 2013 from cu19 to cu23. setup fails with the following error code:
Unable to remove product with code 4934d1ea-be46-48b1-8847-f1af20e892c1. Fatal error during installation. Error code is 1603. Last error reported by the MSI package is 'The specified account already exists.
I have googled this error but it has not lead me to a solution. I have tried running the tool that fixes issues with programs being installed found here with no luck: https://support.microsoft.com/en-us/help/17588/windows-fix-problems-that-block-programs-being-installed-or-removed
I am hoping someone will be able to assist.
