Common SEM Opening Problems

Alpha Anywhere - Alpha Software Isn't There

You encounter an error message such as "%%os%% Can't Open SEM Files" when trying to open your SEM. Generally, this is experienced in %%os%% because Alpha Anywhere - Alpha Software isn't installed on your PC. Because your operating system doesn't know what to do with this file, you won't be able to open it by double-clicking.


Tip: If you don't have Alpha Anywhere - Alpha Software installed, and you know of another program to open your SEM file, you can try opening it by selecting from the programs listed under "Show Apps".


Alpha Anywhere - Alpha Software is Out-of-Date

Sometimes your installed version of Alpha Anywhere - Alpha Software won't support your Alpha Five Set Data Dictionary Memo File file. Visit the Alpha Software website to download (or purchase) the latest version of Alpha Anywhere - Alpha Software. This issue mainly occurs when your Alpha Five Set Data Dictionary Memo File file was created by a newer version of Alpha Anywhere - Alpha Software than you have on your PC.


Tip: If you right-click on your SEM file, then select "Properties" (Windows) or "Get Info" (Mac), you can obtain hints about what version you need.


Summary: Not having the right Alpha Anywhere - Alpha Software version on your computer can cause problems opening SEM files.


Other SEM File Issues

Errors opening Alpha Five Set Data Dictionary Memo File files can still occur even with the latest Alpha Anywhere - Alpha Software software installed on your computer. Other SEM opening errors can be created by other system problems inside of %%os%%. Problems unrelated to software:

  • Accidental deletion of the description of the SEM file in the Windows registry
  • Incomplete or bad installation of a software application associated with the SEM format
  • Something has caused file corruption of your SEM
  • Your SEM has adversely impacted by malware
