Scenario

You’re trying to install one of our products, and the following error pops up:

“The installer has encountered an unexpected error installing this package. This may indicate a problem with this package. The error code is 26352.”

Reason

Most likely, the problem is that the Paragon certificates stored in the Trusted Publishers repository for the current user, have been previously installed in the Local Machine repository, so when the .msi is installed, the regular user even with admin privileges does not have enough rights to replace the certificate in LocalMachine/GroupPolicy store, and this leads to crash.

Solution 1

Delete obsolete Paragon certificates using certmgr.

Solution 2

Delete obsolete Paragon certificates using Certificates snap-in.

Launch “Run” utility (Win + R), type mmc, press Enter
Select File – Add/Remove Snap-in
A window will appear on left. Select Certificates, click Add
A window will appear. Select Computer account and press Next
Select Local computer and press Finish
A window with certificate stores will open. Select the root of the Certificates, click on the item, go to View – Options in drop-down list
Select Certificate purpose and press OK
Find the Code Signing repository and see if there are Paragon certificates
If there are none, you can also search the whole tree by clicking on the Certificates root and selecting Find Certificates
In Contains field, enter Paragon, and in the Look in Field field, choose Issued to
At the bottom of the window, you should see all the certificates installed in the stores. The ones seen on the screenshot can be deleted
Try installing the software again.
