  • CA Service Desk Manager


  • CA Service Desk Manager:Release:12.6 CA SDM
  • CA Service Desk Manager:Release:12.7 CA SDM
  • CA Service Desk Manager:Release:12.9 CA SDM
  • CA Service Desk Manager:Release:14.1
  • CA Service Desk Manager:Release:17.0



If you run any CA Service Desk command, such as pdm_configure, pdm_status etc., the following error appears:


CA Service Desk Manager 12.x, 14.x and 17.0 All Supported Windows Operating Systems

Improper file format of the NX_ROOT\NX.ENV file


The reason why this error appears is because the NX_ROOT\NX.ENV was edited manually and was not saved in the right encoding.

If the file is saved in "UTF-8", "Unicode" or "Unicode big endian" encoding, the Visual C++ error will appear. 

The supported and correct encoding format for the NX.ENV file is "ANSI". 



Once the NX_ROOT\NX.ENV file has been saved with the proper encoding and the CA SDM services recycled, the error will no longer occur when attempting to run CA SDM commands.
