Hello MaryKy, try to delete all the past folders you might have in your device (including the trashbin) and again the client. Before extracting the files, disable your antivirus or add a firewall exception to the PRO client and extract it.
If it doesn't work try to do the same steps and but this time download the x64 client.
Hope this was able to help and let me know how it turned out by quoting me in this thread.
Thank you very much everything is ok now!!! :Grin:
