Peter, this is what I did:
I downloaded the FSUIPC4.zip file from your site few days ago and placed it in a folder that contained an old FSUIPC4.zip ( !!!!!!!)
I did the payment accordingly and received the registration number from""" https://secure.simmarket.com/account_hi_id=618012"""
I opened the folder and executed the installation and then registered as per instruccions....after that, it gave me that messages as explained before, fine.
Today, as requested, I tried unsucsesfully to find the installation log file, so in the meantime I removed the folder FSUIPC4.zip. Then dowloaded again the FSUIPC4.zip from your site, installed but during the installation, when it asked me for what I want to do with the registration, I decided to remove the old registration just in case, registered again and......voila....!!!
The isntalled version now IS the 4.60, ...........dont ask me what I did wrong, sorry to bother you with thid "glitch" but thanks for your support
Daniel
