After I used the already existing topics in here that related to my problem I have now been able to reinstall local, and get it up and running again.
Here is the solution that worked for me:
I had to completely delete local, including the app, website files and the hidden configuration file in appdata>roaming>local. (You might have to stop processes that use it)
Once that was deleted I reinstalled it again on my main C disk(SSD) and local could be installed and I could also open up the program.
Now I can get back to using your amazing program guys!
