Solved Win8.1 InforPath Error

I am running Win8.1. When I try to open a file with a .HTM suffix, I get an InfoPath error indicating that something is wrong with the file. If I open my browser (FireFox) and open the file from "inside" Firefox, the file opens fine.

What is Info path? A brief web search suggests that it is related to forms and such. Any thoughts on what might be wrong?

Thanks

I suggest you read this:

HTM File (What It Is & How To Open One)

Thanks for the prompt reply. I did not ask the question clearly ...

I have 40 years experience with computers and am a webmaster on several web sites. I know lots about htm files and develop htm code daily. I know what InfoPath is within the MS Office suite of applications, i.e., it is essentially a forms generator that outputs xml files. I prefer to use the VBA forms capability integrated into the other office tools so I have not done much with InfoPath.

I am fairly new to Win8 and have not encountered a similar problem on any previous operating systems. I presently have three computers running WinXP and one running Win7. the same files that are problems on the Win8.1 system open fine on any of my other computers.

I have found the problem ... Win8 (at least as originally configured on my computer) associates all htm and html files with InfoPath (seems strange) or perhaps that happened when I loaded MS Office. Previous versions of Windows associated htm and html files with the default browser. I changed the default file association to be the default browser and everything now works as it should

Glad you got it sorted out. This will help others who may have the same problem.
