I am a newbie to QNX development (taking over an old project).  Something has changed, and I don't know what, and I am 
no longer able to compile anything.

I am using the QNX SDP 6.4.1 on a Windows 10 PC.  Every compile fails with the following message:

'-p' is not recognized as an internal or external command,
operable program or batch file.
*********************************************************
Your software must be activated, run the "qnxactivate" application to activate.

*********************************************************
license check failed

Even if I run qcc by itself on the command line, with no options, I get the same error.  I do have a valid license:

C:\Users\myusername>showlicense

The currently active license is: Commercial

The text corresponding to this license can be found in:

C:\QNX641\install\qnxsdp\6.4.1\licenseCommercial.txt

Any ideas on how to toubleshoot this?

Thanks!
