Unknown File Type

Unknown File Type

If the user is getting “Unknown File Type” while generating any Reports through Income Tax Auditor or TDS software or either MAIN system or LAN system, then the reason would be that the software was not updated successfully.

The report for which the issue is occurring can be resolved following the process given below:

If the issue occurs in IT Auditor:

  1. Open www.kdkupdate.com
  2. Download Serial No. 5 (Zen IT Auditor)
  3. Extract the downloaded file.
  4. Copy the files and contents of the folder and paste to the root location of the software:

(Root Location:- Right Click on the Icon of the software and “Open File Location”)

              "C:\Program Files (x86)\K.D.K. Software\Spectrum\Zen IT"    


            "C:\Program Files\K.D.K. Software\Spectrum\Zen IT"


  1. Download "DLL-Full" file given on serial no 21 (www.kdkupdate.com ).
  2. Extract the "DLL-Full.zip" and copy all the contents of DLL files given inside the folder and paste them at either location given below:

"C:\Windows\System32" for 32-bit system"    


C:\Windows\SysWOW64" for 64-bit system"

Similarly, if the issue is with TDS software, then it is required to update the TDS software in similar fashion by downloading Serial No. 7 (Zen TDS) 

NOTE:- The same process is for both the system whether being the MAIN system or the LAN system.
