Did you install recently and this is your first time updating?
This usually means that when you first installed the software you used a _update patch instead of a full _setup file.
Reinstall HM2 from this file - http://www.holdemmanager.com/Downloa...ager2Setup.exe
After downloading, right-click the file, go to properties and click unblock. Then, right click the file and run as administrator to complete the reinstall.
If you continue to have problems:
Create a backup of your settings by following this FAQ - http://hm2faq.holdemmanager.com/ques...+settings+ONLY
Uninstall HM2 and then Reinstall HM2 from this file http://www.holdemmanager.com/downloa...er_2_Setup.exe
After downloading, right-click the file, go to properties and click unblock. Then, right click the file and run as administrator to complete the reinstall.
Then try the beta auto update again or the update link for 8268 in the OP.
