MSI Update to Build 17318 fails with error 1638

Thread needs solution

Hello again,

I'm trying to get the beta 17311 updated to beta 17318. The installation manual says (if I understood correctly) that for an update with MSI-Deployment you need to add "ADDLOCAL=ALL" to the properties on the msiexec-Commandline.

Well it doesn't work - it errors out with MSI error 1638 (Another version of the product is already installed). Interestingly this worked fine when upgrading from the first release to beta 17311.

Did I miss something? In B&R10 there were some undocumented properties you had to add to make it work - is this the same with B&R11 now?

aah found it. It's not in the documentation, but it's in a KB that looks related:
http://kb.acronis.com/content/1646
The properties are "REINSTALL=ALL REINSTALLMODE=vomus"

Please consider adding this information to the installation guide.
