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

Question

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:

     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

     AppData\Roaming\WwiseLauncher

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?

Hey! I got this error after accidentally hiding my appdata files. Check to make sure your files are not hidden in properties.

Hi , turn on the Windows Firewall ( Брандмауэр ) (brick wall with a globe)

Hi! In downloading process I found this error.

Anyone knows how can I fix it?
Thanks.

Answer 1

Hi,

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 ?

http://www.audiokinetic.com/download/WwiseLauncher-2020.3.2.msi

Thanks !

If it helps it looks like I currently have MVC++ 2015-2019 Redistributable (x64) - 14.28.29334 installed, whereas you are trying to download 14.22.27821. Is this a huge issue having a newer version?

I get a 0x80070666 error forcibly trying to install the older version out side of your launcher.

Hi Ollie,

I'm really sorry that you are facing these issues!

Having a newer version of the redistributable should not cause any issues. Judging by the log, the error is not caused by a concrete redistributable failing.

Could you by any chance share the path at which you are trying to install Wwise? Would installing it in a different location change anything?

Thanks

---

I try to install Wwise to "C:\Program Files (x86)\AudioKinetic\Wwise" I remove the version ID from the folder name so that I don't have to keep updating the path in UE4.

---

Thank you!

We don't have the exact cause for the issue you're facing yet, and are trying to reproduce it on our side to ensure we can address it.

Do you have a folder at C:\Users\<User>\AppData\Local\Temp\WwiseLauncher\wwise.2021_1_0_7575_prerequisites? It should contain the installation packages for the redistributables (vc2015_2019redist_x64.exe in your case).

Also, could you please check the value of the ComSpec environmental variable on your PC? It should be "C:\Windows\System32\cmd.exe" or something similar.

---

Yes, I do see that folder and that specific file.

ComSpec is currently set to:- %SystemRoot%\system32\cmd.exe

If there is any way that I can hep you by sharing my desktop and investigating the issue please let me know.

Answer 2

Try to install Visual studio 2017
