I'm trying to install the trial of Corel Video Studio X3 and it unpacks, and then it allows me to accept the terms, and choose what I want installed (the flash player, updates, ect.). I click next and it seems like it's gonna start and then it says this and stops: "this installation is forbidden by system policy. contact your system administrator". Yes I am logged on as an administrator. I tried this and it didn't help: 1. Click Start on the Windows taskbar, and then click Run. 2. On the Run window, type gpedit.msc, and then click OK. 3. On the Group Policy window, navigate to Local Computer Policy, then Computer Configuration, then Administrative Templates, then Windows Components, and then Windows Installer. 4. Double-click Prohibit non-administrators from applying vendor signed updates. 5. Click Disabled, and then click OK. I also tried this and it didn't help either: 1. Click Start -> Control Panel 2. Open Administrative Tools 3. Open Local Security Settings 4. Click Software Restriction Policies 5. If no software restrictions are defined, right click the Software Restriction Policies node and select New Software Restriction Policy 6. Double click Enforcement 7. Select "All users except local administrators" 8. Click OK 9. Reboot the machine1 person needs an answerI do too

I've now tried this too (and it didn't work): 1. Download and install subinacl.exe. 2. Create a file called reset.cmd with Notepad. Copy the text below into the file reset.cmd and run reset.cmd with administrative rights (it may take a LONG time): cd /d "%ProgramFiles%\Windows Resource Kits\Tools" subinacl /subkeyreg HKEY_LOCAL_MACHINE /grant=administrators=f /grant=system=f subinacl /subkeyreg HKEY_CURRENT_USER /grant=administrators=f /grant=system=f subinacl /subkeyreg HKEY_CLASSES_ROOT /grant=administrators=f /grant=system=f subinacl /subdirectories %SystemDrive% /grant=administrators=f /grant=system=f subinacl /subdirectories %windir%*.* /grant=administrators=f /grant=system=f secedit /configure /cfg %windir%\inf\defltbase.inf /db defltbase.sdb /verbose
