Troubleshoot TRG Files
Issues Opening TRG Files
Norton SystemWorks Not Present
You attempt to load your TRG file and get an error such as "%%os%% Can't Open The TRG File Extension". Usually, this is because you do not have Norton SystemWorks for %%os%% installed. You won't be able to double-click to open your TRG because your OS doesn't know what to do with it.
Tip: If you know of another program that can open your TRG file, you can try opening it by selecting the application from the programs listed.
Norton SystemWorks is Out-of-Date
It is possible that your version of Norton SystemWorks isn't able to open your Symantec LiveUpdate File file due to incompatibility. Visit the Symantec Corporation website to download (or purchase) the latest version of Norton SystemWorks. Your Symantec LiveUpdate File file was probably created by a newer release of Norton SystemWorks than what's currently installed your computer.
Tip: Find clues on the correct software version by right-clicking your TRG file and clicking "Properties".
Regardless, most of the TRG file opening problems relate to not having the right version of Norton SystemWorks installed.
More Causes of Problems Opening TRGs
Although you might already have Norton SystemWorks or another TRG-associated software installed on your computer, you can still encounter problems opening Symantec LiveUpdate File files. There can be other issues - unrelated to software - preventing you from opening TRG files. Other contributing causes:
- TRG file references in the Windows Registry are broken
- Corruption of the TRG file description inside the Registry
- Defective install of a TRG program, such as Norton SystemWorks
- Your TRG can't be loaded properly (file corruption)
- The TRG is infected with a virus
- Hardware related to TRGs has device driver corruption
- Your PC doesn’t have enough available resources to open the Symantec LiveUpdate File file
