Yes, you should just be able to run the installer again. What I'd suggest you do is two things:
1. Backup the current WinGate registry. Do this by opening regedit and exporting the key "HKEY_LOCAL_MACHINE\Software\Qbik Software\WinGate". Then, you can always revert back if you run into any problems.
2. 4.5.1 is a fairly old version, you can use the same license key with 5.2.2 and still get the benefit of all the bug fixes, stability improvements and so on.
