Preview Handler Error 80040154 REGDB_E_CLASSNOTREG
I recently created an Icon Handler which turned out to work without any problems. I then tried to create a Preview Handler but when I loaded it into the test shell and clicked on the associated file type I got a 80040154 REGDB_E_CLASSNOTREG Error. I thought
maybe I did something wrong and tried to do it again with the help of the tutorial on codeproject, but I still got the same error. I then downloaded the SharpShell Samples from github and built them. Tested it and also got the same error. I really don't get
why my Icon Handler works but the Preview Handlers don't. Maybe there is something wrong with my system?
