Desktop Startup Error

I am using desktop version 21.10.3 on windows.

Sometimes when starting the program I get this error, but not always. I usualy hit quit and re-start it and it works fine. Lately however its been coming up frequently and I wonder what the issue could be.

error

Can you expand Details button? That contains more useful info.

Here is the coppied text from the error:

Thank you, so assume you installed Download | Manager

I believe this is the same issue that was brought up a while ago in this topic.

I have been experiencing the same thing since that topic was brought up nearly a year ago, but only on one of the two computers on which I use Manager. In that time I have updated Windows and Manager several times. I am now on Desktop version 21.10.6 of Manager and Windows 10 version 20H2.

I was about to post to the above topic to see if anyone else is still experiencing the issue, as this morning it took me about four attempts and 20 minutes to open Manager. Each time it gives the error it appears to be loading for a while before the message appears, which is why it takes so long.

@Kelvin and I seem to have fairly similar specs:

in Windows, there is a high chance of issues with user permissions.

@Kelvin looks like you have installed Manager to the default location which is your Users folder. Can you try uninstalling Manager completely and then do a fresh install to another drive which is not your system drive? check if the problem persists. make sure you make a backup of your business data first.

@GrahamvdR have you installed Manager in your Users folder?

@sharpdrivetek Yes, in C:\Users\graha\Dropbox\Manager.
