Unable to Install Update

[StuartR]

Good evening.  JamKazam has been my musical lifeline during these "unprecedented times". I've practiced with others a few times a week without any problems since I first got connected in late March. 

When I opened JK for practice on Sunday there was a required update - no big deal, I've needed to update prior to several sessions over the past couple months & it has never been a problem until now.  Apparently despite zero issues practicing Thur 6/25 the file from the prior update (1.0.3744) has gone completely missing from my computer. 

When I try to install the 1.0.3787 update I get this error message: 
The path 'C:Users\AppData\Local\Temp\JamKazam-1.0.3744.msi' cannot be found. Verify that you have access to this location and try again. or try to find the installation package 'JamKazam-1.0.3744.msi' in a folder from which you can install the product JamKazam 1.0.3744.

I tried deleting the update & downloading/installing again. Same result.

I've tried completely uninstalling JK (& my interface driver because I saw that in someone's post) and running a Registry cleaner in an attempt to start fresh but I can't even fully uninstall due to that same "path" error.

Is there any way for me to start fresh when I've somehow mysteriously lost a prior update/install?

After a couple days of frustration I am at wit's end and would appreciate any help that I can get!

Try this approach.... Go into Add/Remove programs and uninstall your current JK client. Now go to the JK website and manually download the latest client. Let us know how it goes.
