Can I have the screenshot I asked for please? That helps me start to identify the potential issue.

 

 

 

This is dealt with in the FAQ at the top of this thread:

 

Extracting the file will take a while, but it shouldn't take the hours and hours that the program extracting will sometimes say it will. To speed it up, it is recommended that you have as few programs running as possible so that the system can dedicate as many resources to the extraction as it possibly can.

Secondly, for files as large as this, the calculation of the extraction time will be wildly incorrect at the start. After a while, it'll show a more realistic timeframe, which shouldn't be more than an hour or two if you have a good setup and few programs running at the same time.
