Please check that your 'unins000.dat' and 'unins000.exe' is not hidden. In Windows check that the folder display options is not set to 'Hide extensions for known file types'.
If you still do not have the files in the tng folder:
Download and unrar: save in the folder 'C:\Program Files\datatex\tng'.
Steps to uninstall TNG:
- Run the 'unins000.exe'.
- Once uninstall complete, check that the TNG service is not listed under Administrative Tools -> Services. If not, you can now rename/delete the TNG folder.
The TNG service was not uninstalled, service files removed
How do I re-install/move TNG?
