chlorophyll Posted December 7, 2009 Share Posted December 7, 2009 While it has received indisputable accolades as Microsoft’s best operating system to date, Windows 7 is no stranger to problems either, albeit to an extremely smaller degree than its predecessor, Windows Vista. Some of the issues reported by Microsoft involve failed Vista to Windows 7 upgrade attempts, which can happen because of a variety of reasons. In this regard, popular optical media emulation software Daemon Tools and Alcohol 120% have also been identified as not exactly playing nice with Windows 7 upgrades from Vista. According to the Redmond giant, at fault aren’t really the two applications, but rather a driver that ships with the emulation solutions, as well as with additional pieces of software.“A rollback may (…) occur when the third-party driver Sptd.sys is installed on the computer. This driver is distributed with several applications such as Daemon Tools and Alcohol 120%. We recommend that you temporarily uninstall third-party CD/DVD Authoring or Virtualization software that could contain this driver before you upgrade the computer to Windows 7,” Microsoft noted.In the past, the software giant identified Intel storage drivers as well as the unresponsive Iphlpsvc service as causes that can generate upgrade failures for users attempting to move their computers from Vista to the latest iteration of the Windows client. Generally, the symptoms experienced by end users are extremely similar, namely the Windows 7 upgrade process will fail to complete and the machine will be subsequently rolled back to Vista. According to Microsoft, system memory issues or problems with the hard disk can also prevent Windows 7 successful upgrades.“Check the computer's memory for errors: Run the Windows Memory Diagnostic tool to check for memory problems. To do this, follow these steps: Close all open programs. Click Start, click Control Panel, click System and Security, and then click Administrative Tools. Double-click Windows Memory Diagnostic. When you are prompt, click Restart now and check for problems.If the Windows Memory Diagnostic tool returns an error, this indicates there are problems with the memory on the computer,” Microsoft explained.In addition, users can check for hard disk problems. In order to do so they have the Chkdsk tool included in Windows. Users need to make their way to the system drive, right-click it and select Properties. “On the Tools tab, click the Check Now in the Error-checking area. Click to select both the Automatically fix file system errors check box and the Scan for and attempt recovery of bad sectors check box. Click Start. If you receive the following message, click Schedule disk check, and then restart the computer. ‘Windows can't check the disk while it's in use. Do you want to schedule the disk check to occur the next time you restart the computer?’” Microsoft stated. Link to comment Share on other sites More sharing options...

HX1 Posted December 7, 2009 Share Posted December 7, 2009 You know.. even with XP, I have issues with these two programs.. I don't archive them nor use them.. I remember why I was attempting to use Alchohol 120%.. and Daemon Tools I think had something to do with PS2 emulator of some sort.. but never worked out.. Just caused big problems..IMO.. There are many better suited alternatives to these two.. that do everything you need.. with the right one.. Link to comment Share on other sites More sharing options...
Night Owl Posted December 7, 2009 Share Posted December 7, 2009 I also had a problem on XP with Alcohol 120%. I was trying to do a boot-time defrag with PerfectDisk, but it didn't work at all. I found out that my slightly older version of Alcohol 120% had an older Sptd.sys driver. I had to upgrade Alcohol 120% to the very latest version to get the latest Sptd.sys driver. PerfectDisk worked fine after that.Daemon Tools/Alcohol 120Sptd.sysDuplexSecure, the developers of the sptd driver, have released an updated driver (v1.29) that no longer prevents PerfectDisk's boot time defrag from running. Please go to http://www.duplexsecure.com/downloads to download the updated driver.Source: PerfectDisk Knowledge Base Link to comment Share on other sites More sharing options...
