Hello I'm new to Blender and would like to know about this one error I get with Python. The version for Blender I have is 2.49b and the version I tried to install was 2.6.5. The error comes out as this:

An error occurred during the installation of assembly 'Microsoft.VC90.CRT,version="9.0.21002.8",publicKeyToken="1fc8b3b9a1e18e3b",processorArchitecture="x86",type="win32"". Please refer to Help and Support for more information.

Now the reason why I'm using these versions of Blender and Python is because I want to make weapon mods for Elder Scrolls IV Obivilion. Also about this error I did some searching on Google and it turns out that is an error within Windows. One of the members brought up two methods both on which I tried and ended up in failure. I was told from a friend that there are people on this site that know about Python and I was wondering if they could point me to the right direction. I want to be able to create and give Blender and Python a fair chance and if anyone can show me what I can do to make this work that would be wonderful for me.

Hello KiteMaster

First welcome to the Blender Forum here at Renderosity. Now I am running 2.49b and Have the latest Blender 2.72b but have run almost each of the new versions of Blender since 2.5. Do you have python installed on your system? Are you running 2.65 from a folder or actually installed on the system? And what are your system specs what OS are you running and is it 32 or 64 bit OS? I know with the install of 2.49 you have to have python actually installed on your system Python 2.6 but if you run it only from a folder instead of an actual install you do not need python installed. Check insode of your installed 2.49 and check if you have the following two files Microsoft.VC90.CRT.manifest & Microsoft.VC90.OpenMP.manifest these two files may have become corrupt and may need to be replace and think the only way to replace them is from a fresh install of 2.49.

first question would be what version of either blender are you using?

newer versions are available in 32 bit and 64 bit and if you have a 64 bit system and download a 32 bit software it will not work right sometimes because it downloads into the x64 files and not the x84 files where it needs to register

if by chance you got one of the OS or ubuntu versions they will not register at all

check which version you have and need and make sure that they are compatible

also do all windows updates and retry the download

I hava Windows 7 64 bit and I found the two folders you mentioned so I uninstalled Blender and plan on reinstalling it as for Python the second window that show up for Blender says this:

Compiled with Python version 2.6.2

' import site' failed; use -v for traceback

Checking for installed Python... No installed Python found.

Only built-in modules are available. Some scriptes my not run.

Continuing happily.

The thing is I know that I didn't installed Python but that error I mentioned before is preventing me from doing that. Also I tried installing the Windows updates and it keeps giving me an error code and I've been dealing with it for months.

Hello KiteMaster

I was finally able to reproduce the same error when running 2.49b from with in a folder and installed. I have another custom build version of 2.49b that has the python libraries built into the installer. So you will need to install not the most current of python but version 2.6.2 or 2.6.6 of python since that is the build version that Blender 2.49b was built on. You don't need to install that python version unless you have scripts or add on that depend on it being installed. I found this link in the old online manual that explains the procedure for how to set up Blender to see and find your newly installed Python path http://wiki.blender.org/index.php/Doc:2.4/Manual/Introduction/Installing_Blender/Python

Ok I'll look into it when I get the chance also thank you for taking the time into helping me.

Your welcome do let us know if that solves the problem

Good Luck

<span>Bonjour, my friend.  I am interested to understand if you solve the problem.<br></br></span>

Well after a couple of tries I got a version of Python installed that was part of the 2.6 series but it wasn't 2.6.2 or 2.6.6 it was 2.6.0. When I went to reinstall Blender it said I needed to install Python 2.6 so I decided to go install 2.6.0 since 2.6.2 was producing the same error as 2.6.2. After installing I started Blender and the message for the second window was this:

Compiled with Python version 2.6.2.

Checking for installed Python... got it!

Me again I meant 2.6.6 in the second sentence after error as.

 well you had me confused and I thought you wanted to use blender 2.4x and had probs with a python addon

now your loading 2.6x .... and still got the error ??

is no need to install blender OR python !! just grab the zip unpack and run blender.exe

blender 2.5 plus probably wont run a 2.4x addon, I "think" blender 2.4x will have its own python in zip (unbrokenfighter will tell me if I'm wrong) so grab the zip of that version and try then

I don't "do" games but most will import a .obj just a lot more messing about without a "exporter/importer" addon

Hi Heddheld No 2.49 does not come with python unless you are getting a custom build one with the python libraries packed inside the zip. I did replicate the same error KiteMaster was getting and installed python 2.66 and the error went away. Add-ons made for Blender versions prior to 2.50 will not work in the current versions of Blender. I uninstalled Blender 2.49 installed python version 2.66 and reinstalled Blender 2.49b and the error no longer came up. You really do not need to actually install python for this version of Blender unless you have a specific add-on that requires the python libraries. I run 2.49b only for some backward compatibility on projects that I made and used with in Second Life (whole other story lol)
