How to solve "Installation failed: error installing prerequisites" error on the PC?

0 votes

Even though I had recently upgraded to the latest version of Wwise successfully, (2019.2.8.7432), I had to attempt a re-install to get additional data for a new platform that we are now supporting. Unfortunately I am now continually seeing: -

     Install operation completed with errors:


          Installation failed: error installing prerequisites

The relevant log information seems to be: -

It is also odd that in my Appdata \ Roaming folder I am seeing 2 Wwise Launcher related folders: -

     AppData\Roaming\Wwise Launcher


These exist even after uninstalling the previous version of the tool and deleting any existing folder references to Wwise.

It also seems like my launcher installation has moved from "Program Files (x86)" to "Program Files".

This is the first time that I have had an issue like this upgrading Wwise. Has anyone else seen this and do you have any suggestions for a solution?

Dear Ollie, Can you confirm the special build by Denys fixes the issue?

We are currently working on this issue and think that we might have found a solution, would you care to test this version of the Wwise Launcher and let us know if it fixes the issue ?

Thanks !
