Issue:
When attempting to connect to Sepam units using the SFT2841 software, the user notices that the software launches with a "Beta" suffix in its name. Upon connection attempt, an error message appears stating that the Sepam series application cannot be found.
Root cause:
This issue is caused by invalid or missing registry keys in Windows. These keys may be inadvertently modified or overwritten by other software installations, such as Easergy Studio or CET850. In such cases, the SFT2841 registry subkey may be renamed to SFT2841Temp, preventing proper detection and operation of the software.
Temporary workaround:
Option 1:
Manually rename the registry subkey:
- In Registry Editor navigate to:
HKEY_LOCAL_MACHINE\SOFTWARE\WOW6432Node\Schneider Electric\ - Rename “SFT2841Temp” to “SFT2841”.
- Rename “SharedTemp” to “Shared”.
Option 2:
- Open a text editor and paste the following content:
reg copy "HKEY_LOCAL_MACHINE\SOFTWARE\WOW6432Node\Schneider Electric\SFT2841Temp" "HKEY_LOCAL_MACHINE\SOFTWARE\WOW6432Node\Schneider Electric\SFT2841" /s
reg copy "HKEY_LOCAL_MACHINE\SOFTWARE\WOW6432Node\Schneider Electric\SharedTemp" "HKEY_LOCAL_MACHINE\SOFTWARE\WOW6432Node\Schneider Electric\Shared" /s
reg delete "HKEY_LOCAL_MACHINE\SOFTWARE\WOW6432Node\Schneider Electric\SFT2841Temp" /f
reg delete "HKEY_LOCAL_MACHINE\SOFTWARE\WOW6432Node\Schneider Electric\SharedTemp" /f
- Save the file with a .bat extension, for example: SFT2841_CorrectRegistry.bat
- Run the batch file as Administrator to apply the fix.
This restores the correct registry keys and allows SFT2841 to function normally. If you have any questions, please contact Schneider Technical Support.
Final resolution:
Future software releases will include fixes to prevent this issue from occurring.
