I am running Windows 11, and have installed KiCad 5.0, 6.0, and 7.0.
When I right click on a file the open with menu reads KiCad 7.0 for all 3 versions of the KiCad file.
In the End I had to delete the Registry settings for:
“Computer\HKEY_CLASSES_ROOT\Applications\kicad.exe”
“Computer\HKEY_CLASSES_ROOT\Applications\eeschema.exe”
“Computer\HKEY_CLASSES_ROOT\Applications\pcbnew.exe”
“Computer\HKEY_CLASSES_ROOT\Applications\gerbview.exe”
Had something like that when transitioned from V5 to V6, or maybe from V6 to V6.99. App icons were swapped also (thought launching V6 but V5 was launched, something like that). Do not remember exactly, but all this was related to “open with” windows functionality, got rid of V5 solved the issue.
Same for me. I have 6.0.x, 7.0.0 and 7.99 in parallel and it was all 7.99. Deleting said registry keys solved the issue. Now the context menu offers 6.0.10, 7.0 and 7.99 all right.
