Pri pokuse o pridanie alebo odstránenie programu sa zobrazí chybové hlásenie „Chyba 1719: Nedá sa získať prístup k Inštalátoru systému Windows"

When you install as much software as most of the staffers at the Planet do, you sometimes run into that little glitch that brings things to a halt and makes you scratch your head. Error 1719 is one of them.

Error 1719 occurs when the msiexec.exe program becomes disassociated with .msi files. Under Windows XP x32 this is usually fixed with rebooting into safe mode, renaming the msiexec and DLL's and letting Windows File Protection reinstall them. This doesn't always work in x64.

Error 1719 occurs in x64 when the 32-bit version of msiexec is registered as the msiserver. Here's the fix:

1. Open regedit ( Start -> Run -> regedit.exe -> OK)
2. Go to the following key: My computer\HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\MSIServer
3. Look at the ImagePath entry. For Windows XP x64 it should read:
CODE
C:\WINDOWS\SysWOW64\msiexec.exe /V

If it doesn't edit the registry to match that.
4. Restart the Windows Installer service from the Admin Control Panel -> Services CP

That's all there is to it! It took me a while researching this and it dawned on me that some utilities might find the above entry wrong and reset it to it's 32-bit counterpart. Thats what caused the error as 32-bit msiexec cannot run as a installer for 64-bit apps.
