error occurred during the installation of assembly microsoft vc80 crt

So here we are with that error and where it comes from. Please refer to Help and Support for more information. As a matter of fact, here is the original error from that Visual C++ 2005 Redistributable:Įrror 1935.An error occurred during the installation of assembly ',type='win32',version='7.42', publicKeyToken='1fc8b3b9a1e18e3b',processorArchitecture='amd64''. So globally, it can happen with any “recent” Windows version, from XP to Vista.įrom the look of it, I assumed this was once again an issue related to some Visual C++ Redistributable package, and after trying quite a few I eventually tracked it down to Microsoft Visual C++ 2005 SP1 Redistributable Package (圆4 in my case).

Some researched showed me that this can occur on various other Windows versions: Vista 32 bits, probably Windows XP ( here’s a sure one), another one on an unspecified flavor of Windows 7, etc.

When installing the latest Graphviz (graphviz-2.26.3.msi) on Windows 7 圆4, I got blocked by the following error:Īn error occurred during the installation of assembly ',type='win32',version='7.42', publicKeyToken='1fc8b3b9a1e18e3b',processorArchitecture='amd64''. If you’re still with me, on with the problem and its solution 🙂 The problem You’ll notably need some secondary OS (the easiest/fastest way is probably to grab an installation CD of Ubuntu and use it as a liveCD), and be ready to use it to manipulate some Windows system files (folder, actually)… It will very likely upset some of your programs, too, even though on my computer all ended well in the end (but at some point, my PC Tools Firewall did complain a little).

Ok, before even starting I have to tell you this is a long, tedious and probably (quite likely) not 100% reliable solution.
