proe5.0安装keyshot接口后出现以下错误  求解


**********************************************************
    Installing KeyShot Pro/E Plugin Install Results     
**********************************************************

**********************************************************
Moving the file
D:\KeyShot\proe\proe5.0\wf5\protk.dat
To
D:\PTC\proeWildfire 5.0\text\protk.dat
Failed.
**********************************************************

**********************************************************

The Protk.dat file is needed to allow Pro/E to locate the proper plug-ins
The installer may fail to copy protk.dat to the appropriate location due to one of the following reasons:

** The destination directory is write-protected.
** A copy of protk.dat already exists in the destination location.
** The installer was not able to find Pro/E information in the registry

To complete the installation, please move the file protk.dat
to location of the destination text directory. For example: C:\Program Files\proeWildfire 3.0\text

If the protk.dat file already exists, you need to merge the above mentioned protk.dat file with this file.
Merging can be accomplished by copying the contents of the protk.dat text to the top of the destination file.
