AbiWord _Portable_2.4.5.exe is not supported archive.
I am having a problem extracting my previously downloaded AbiWord_Portable_2.4.5.exe file.
When I double click the file I get the expected "7-Zip self-extracting archive" dialogue box but when I click the "Extract" button, I constantly get a 7-Zip Diagnostic message dialogue box which indicates that: "C:\..........\AbiWord_Portable_2.4.5.exe is not supported archive.
I have used several Portable Apps before and never encountered this problem in the past and I am familiar with the usual routine of extracting and using these types of applications.
I would appreciate any suggestions as to what the problem could be and how to fix it.
