I am using the below code to get the latest possible pss version. I have Psse34 trial version installed

def latest_pssbin_location():
    import _winreg
    ptiloc = r"SOFTWARE\PTI"
    ptikey = _winreg.OpenKey(_winreg.HKEY_LOCAL_MACHINE, ptiloc, 0, _winreg.KEY_ALL_ACCESS)
    ptikeyinfo = _winreg.QueryInfoKey(ptikey)
    numptisubkeys = ptikeyinfo[0]
    vdict = {}
    for i in range(numptisubkeys):
        vernum = _winreg.EnumKey(ptikey, i)
            n = int(vernum[-2:])

    vers = vdict.keys()
    k = vers[-1]
    lver = vdict[k]
    lverloc = ptiloc + "\\" + lver + "\\" + "Product Paths"
    lverkey = _winreg.OpenKey(_winreg.HKEY_LOCAL_MACHINE, lverloc, 0,_winreg.KEY_READ)
    lverdir, stype = _winreg.QueryValueEx(lverkey, 'PsseInstallPath')

    return lverdir+r"\PSSBIN"

I am getting an error "Error 2" the system cannot find the file specified. How to resolve this?

I know this does not answer the question directly, but if you are simply trying to ascertain PSSE location for psspy, dyntools, etc. you might want to check out the psse library "PSSEPATH". I believe it was created by a forum contributor a few years ago. I have used it on PSSE 32, 33, an 34 with different versions of python. It works great.

Check here:

Instead of using "winreg.HKEYLOCALMACHINE", use "winreg.HKEYCURRENTUSER" and instead of 'PsseInstallPath' use 'PsseExePath'. This is applicable to PSSE 34

For a standard PSSe v34 installation, the original code works fine.
