I'd assume you have already tried this, but make sure your computers both have the old active X redist 9.0c June 2010, located here:

If that doesn't work, launch the THF Patcher found here:

Try downloading this zip, extract it, and then drop the files in your EQ root directory folder. These are all working files, maybe you have a corrupted installation file in one or both PCs:
