Troubleshooting Problems Opening ALT Files
Issues Opening ALT Files
Microsoft Dynamics AX Removed
You encounter an error message such as "%%os%% Can't Open ALT Files" when trying to open your ALT. When this happens, it is commonly due to Microsoft Dynamics AX missing in %%os%%. Your operating system cannot associate your ALT with Microsoft Dynamics AX, so double-clicking the file won't work.
Tip: If you don't have Microsoft Dynamics AX installed, and you know of another program to open your ALT file, you can try opening it by selecting from the programs listed under "Show Apps".
Microsoft Dynamics AX is Out-of-Date
Sometimes your installed version of Microsoft Dynamics AX won't support your Dynamics AX Temporary File file. You will need to download a newer version of Microsoft Dynamics AX if you don't have the right version. This issue mainly occurs when your Dynamics AX Temporary File file was created by a newer version of Microsoft Dynamics AX than you have on your PC.
Tip: Investigate your ALT file by right-clicking and selecting "Properties" to find clues on what version you need.
Regardless, most of the ALT file opening problems relate to not having the right version of Microsoft Dynamics AX installed.
Other Causes of ALT File Opening Problems
