I was eager to try this product out as I have heard good reviews. However, upon installing this x86 software that I downloaded from your website, I am given the follow installation error in a popup which reads: Installation Information - Could not open key: HKEY_LOCAL_MACHINE\Software\Microsoft\Windows\CurrentVersion\Run. Verify that you have sufficient access to that key, or contact your support personnel. I would like to note that I am on Windows XP SP3 and have administrative rights on my user account as it is the only account there is. I have tried to install it in safe mode, but realized I could not, because of Windows Installer. As soon as the setup wizard opens and I click next, ESS informs me that I have a conflicted software installed. However, I do not have any known F-Secure Software installed. I have uninstalled a lot of programs to no avail. My firewall had told me I had a Norton firewall which was also wierd, so I ran Norton's removal tool and successfully removed it. I had previously used Norton. I do not know if this information will help, but I will look to include additional information if you like. I am very interested in testing the capabilities of this program. Thanks! I am quite positive that I do not have any malicious content on my computer and I doubt the F-Secure software, whatever it is, is causing this as well.
