Upgrade for the Jabra Desktop client on Windows 7 32bit fails because of .NET 4

There is a discussion on msdn with an error similar to mine but without any resolution. The error says - Process exited with code -2146762485

Hopefully, someone in this community will be able to help me get past this error.

Solutions Tried

  1. Disabled the firewall and proxy. .NET 4 was downloaded fine but, the install still failed with the same error code.

What OS? Did you try jsut reinstalling the machine? –  TomTom Dec 13 '11 at 15:51
    
As mentioned in the question, it is Windows 7 32bit and NO, I will NOT re-install the machine. I will move to a Mac, before re-installing Windows. –  rht Dec 13 '11 at 16:28

1 Answer 1

The error number -2146762485 appears to be a certificate failure - It's like it's trying to check the signature on the installation file and failing. Is the machine properly connected to the internet/does it have a firewall running?
