Quicktime installation error – Please help

Asked By 30 points N/A Posted on -

Hi guys

I have recently downloaded the latest version of Quicktime on my system because I wanted to see some of the videos.

I started the installation process but during the installation it gives me the following error on my screen:


QuickTime for Windows

An error occurred during the installation of assembly

'Microsot.VCSO.CRT.type='win32'.version ="8.0. 5072


orArchitecture='x86". Please refer to Help and

Support for more information. HRESULT: 0x80070091.


When I press OK, the installation progress bar starts moving in the opposite direction.

Surprisingly after some time I get a message from quicktime that it has been successfully installed but when I try to run the software, it states that the quicktime cannot be started.

I have posted this problem on many quicktime forums but found no authentic solution.

Has anyone else encountered this problem before? If yes please help me out in resolving the issue.

Looking forward to your replies

Can you check this way of doing the installation

First check whether windows modular service is running in services.msc. If it is not running start the service and make sure it is running. Most of the times it may show insufficient system resources error which can be resolved in this way.

Open Regedit and point to this key


In this location you will find a key with name RegistrySizeLimit replace the value of this key to 0xFFFFFF (4294967295) and type to REG_DWORD.

Save the things reboot the system. Once the OS boots up install the QuickTime.
