Error in installing Calibre e-book Management

Asked By 20 points N/A Posted on -


I find a problem on my laptop when I try to install the Calibre ebook management program that applies to Windows/Windows 7/Programs. I am using Windows 7 OS. 

On my laptop (Windows 7), I try to download Calibre. But I am getting the following error message. I've tried downloading from different sites but find the same error: 

An error occurred during the installation of assembly ‘Microsoft.VC90.CRT, Version=”9.0.21022.8”,publicKeyToken=”1fc8b3b9a1e18e3b”,processorArchitecture=”x86”,type=”win32”. 

Please help me. Thanks in advance.

Hi Joanna Mann


Kindly check you have a Visual C++ redistributable 2008 for visual studio2008. If you don’t have one kindly get one or download it from this site that I will be providing.


The reason that you are having that error is because your window failed to update or there are corrupted registry keys in HKEY_local_machine Components

Now after Downloading and installing the program proceed to this next step.


Download this program named “Fix IT”. You can this on this link :


After downloading it just run the program until it reach an error. Get the list of registry keys that this program will give you. * note you will not see any List if your registry keys are not damage.

Now after getting the list of registry key go there locations and delete them all. * NOTE again before removing the registry key make a back up of each of the registry keys. After making a copy of it and delete all the keys that the program give you.

After doing this install again the program that you are trying to install.

Thank you and Good luck.
