Understanding IMP Issues


Typical IMP Opening Challenges

Lotus 1-2-3 Isn't There

If you attempt to load your IMP file, you experience a message such as "Can't Open IMP Files". When this happens, it is commonly due to Lotus 1-2-3 missing in %%os%%. 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 Lotus 1-2-3 installed, and you know of another program to open your IMP file, you can try opening it by selecting from the programs listed under "Show Apps".


Outdated Lotus 1-2-3

In some cases, you might have a newer (or older) version of a Improv Spreadsheet File file that is unsupported by your installed application version. Visit the IBM website to download (or purchase) the latest version of Lotus 1-2-3. This problem is predominately due to having a Improv Spreadsheet File file version that was created by a newer version of Lotus 1-2-3 than what you have installed on your PC.


Tip: You can sometimes get hints about the right program version by right-clicking on the IMP file, selecting "Properties", and looking at the version information.


Primarily, problems experienced when opening IMP files are due to having the incorrect version of Lotus 1-2-3 installed on your computer.


Other IMP File Opening Causes

Errors opening Improv Spreadsheet File files can still occur even with the latest Lotus 1-2-3 software installed on your computer. Other IMP opening errors can be created by other system problems inside of %%os%%. These issues include:

  • IMP file type Registry entries are wrong
  • The IMP file description within the Windows Registry was removed
  • Defective install of a IMP program, such as Lotus 1-2-3
  • Something has caused file corruption of your IMP
  • Your IMP has adversely impacted by malware
  • Drivers associated with IMP software need to be updated
  • Your computer does not have the adequate system resources to open the Improv Spreadsheet File format
