Tekla Tedds 2018 has stopped recognizing my USB Key
Information: USB Keys are no longer available but some legacy users have yet to transition
Symptoms
When launching the Tekla Tedds Application or Tekla Tedds for Word the "Select USB Key" dialog appears (it should only appear if no keys are plugged in) and the list of available keys is empty even though the key is plugged in.
Cause
The problem is occurring because of a change in Windows 10 April 2018 Update which stops the Sentinel RMS system from querying the USB keys correctly. Most applications are not affected because most of the Tekla applications effectively run in Windows Vista compatibility mode even on Windows 10, therefore the April 2018 update does not affect the applications behavior.
The Tedds.exe and Winword.exe (the host process for Tedds for Word) explicitly declare via their embedded manifest files that they are compatible with Windows 10 and therefore do not run in a legacy compatibility mode. Both applications do this because they need to know they are executing on Windows 10 and/or are using Windows 10 specific features.Workaround
Please note: This workaround works for stand alone Tekla Tedds only
Manually change the compatability settings for the Tedds.exe by doing the following:
- Open Windows Explorer and browse to the folder where the Tedds program files are located on your computer which is normally,
- C:\Program Files (x86)\Tekla\Structural\Tedds\
- Right click on the Tedds.exe and then click Properties
- Select the Compatability tab
- In the Compatability Mode group check the "Run the program in compatibility mode for:" and select the "Windows 8" option from the list below
