wine: could not load L"C:\\windows\\system32\\PokerStarsInstall.exe": Module not found

This means you typed something like "wine PokerStarsInstall.exe" into a terminal when the PokerStarsInstall.exe file was not in the same directory. Wine then looked for that program in its system folder, didn't find it, gave up, and quit.

What you should be doing is just navigating to the Poker Stars Installer file, right click it, and hit open with Wine.
