Step 5 - Re-Register urlmon.dll
If you're experiencing errors when using TaxAct Online such as "Error on page" or Java script error" or if you look in the bottom left corner of Internet Explorer and you see a small error that says "Error on page" the first thing that Microsoft recommends is that you re-register a file called "urlmon.dll" with the browser. You can do this as follows:
Click Start, and then click Run.
In the Open box, type Regsvr32 urlmon.dll, and then click OK.
When prompted with the box below, click OK.
