Hi, 

I think that empty C:\QNX641\host\win32\x86\usr\bin folder is an installation error.  Please post installOptionalLog.txt
 and uninstallLog.txt located in %TEMP% directory.

Also, there is a special utility provided with QNX SDP 6.4.1 installation, that can be used to add a new license key: 
Start->Programs->QNX SDP 6.4.1->License Management->Add License.  
So, you should not have to uninstall then re-install the product just to switch the license key.
