Overview:
When I try to install Holdem Manager it says, "Installation package could not be opened."
Solution:
You are getting this error because you're trying to run the installer before extracting it.
Use an unzipping program (Winzip) or the built in one from Windows to extract all the files to a folder. Then run the installer.
To extract the files, do the following:
- Create a temporary folder somewhere in your computer.
- Click on the zipped file and select all the files to be extracted.
- Extract all the files into the temporary folder you set up in step 1.
- Go to the temporary folder and run the installer.
You should now be able to run the installer without getting the error message.
