I wanted to get my system in order before installing Komplete 14 Collectors Edition. I have installed no new products yet.
It has been a long time issue that many existing products would not update with Native Access v1 even after using the NI RegTool. Theyu would remain in the Update tab. I had installed them in non-strndard locations. The installed paths were shown a concatenation of the default path and my chosen path, resulting in an invalid path, and the products could not uninstall when updating. So I removed all products listed under Update in Native Access V1 with NI RegTool. Then I updated to Native Access v2 and ran as Administrator under Win10 and then only 4 programs had updates available. 3 were successfully updated, but Komplete Kontrol would not update. That product had never been an issue before. I used NI RegTool again to remove it from the registry , but it still shows as Update available although I think I have removed it. The error message is 'Installation Failed.Invalid Location'. When looking at the installation path in Native Access, I found that there is no path defined. Therefore, I can neither install nor upgrade.
One more point which may be the cause is that I was altering the default file locations in Native Access while Komplete Kontrol was installing, so I probably caused the problem, but I need to find out how to correct it. I expect something is mucked up in the Windows registry.
