When I try to update or uninstall vMaterials I get an error asking for a missing vmaterials.msi

I have tried to extract the msi file from my original installer but it is not recognized as the correct one. Installed version is 15.3.10173

The problem occurred after my system decided to do a system restore. All my Iray applications stopped working, and this is the final piece I still can not get my head around.
