When opening a Parasolid .x_t file, it tries to install NX11 instead of opening the file. This started to occur after installing NX11 MP1.
Solution
This has been fixed in NX 11.0.2 MP4 (PR#7968326). At the time of this writing, NX 11.0.2 mp13 is the current NX 11 mp.
The following is a workaround if you are running NX 11.0.1.
1. Open a command prompt as admin.
2. cd %UGII_BASE_DIR%\NXBIN
3. regsvr32 NXCam_64.dll
