Open textfile in win8 from 7

Hello, I have a problem.I have a dual boot win8 (64bit) and win7 (32bit). wen i have text file to open in win8 from win7 it will be denied access. all protections are off, uac, in the register different things. Who can help me with this problem?

This has something to do with permission on the file. Right click on the text file->Properties->Security, do you see your name listed under Group or user names. If it's not on the list then click on Edit then click on Add, in the text box , type in Your username, click on Check Names then click OK. Your username should be in the list, now try to open it.

OK, try another way.
Right click on the file->Security->Advanced->Change, Then type in your Username then click Check Names
then click OK, Apply, OK, OK
