After starting the installation, I receive the following error message:
Error finding installer class
This error message can occur if one of the following conditions is true:
- The path to the destination directory or the destination directory itself for MATLAB contains non-ASCII characters (ex: !@#$&^?)
- The path to the Windows TEMP directory, the TEMP directory itself, or TMP variables point to a folder with non-ASCII characters
- The path to the directory containing the installer or the directory itself has non-ASCII characters
- There is a problem with the installation files (corrupt DVD or incomplete downloads)
As a first troubleshooting step for this issue, verify the folder containing the installer only contains ASCII characters and place it on the root of your C drive. If the installer launches then verify that you are installing MATLAB into a folder with ASCII characters only. If you are still experiencing issues, see below for additional troubleshooting:
1) Check the Windows TEMP and TMP variables
To confirm the path for TEMP and TMP under Windows XP/2000:
1. Right click on My Computer and choose Properties
2. Choose the Advanced Tab
3. Click on the Environment Variables Button (bottom left)
In Vista this is accomplished by the following:
1. Right click on Computer and choose Properties
2. Click on Advanced Settings on the left side
3. Click continue on the UAC page
4. Click on the Environment Variables Button (bottom)
Check for the TMP and TEMP variables under both System and User variables. If you see the variable set to a value between percent signs (ex: %TMP%) or to a path with all ASCII characters, the variable is fine. Otherwise, if the varilable have non-ASCII characters such as an exclaimation point (!), these variables can be modified by double clicking on the variable or highlighting it and choosing Edit.
Once changed, reboot the machine and retry the installation.
2) Try the installation in Windows Safe mode.
If the installation folder and the TEMP/TMP folders are all ASCII based, you may be able to resolve this issue by installing MATLAB in Windows Safe Mode. Safe Mode disables hardware drivers and may allow the installation to complete. To enter Safe Mode, reboot the machine. As the machine is booting, tap the F8 key every few seconds until a menu appears. In the menu, select the option for: "Safe Mode with Networking". Log in as normal and try the installation.
3) Try different installation files
If the installer does not work after the workarounds above, the best option is to try different installation files. These can be from a different DVD or via downloads from the MathWorks website. For instructions on how to download, see the related solution: 1-1815H "How do I download licensed MATLAB products from MathWorks website?"
If you are still unable to install after following these steps, contact Installation support here:
the autoinstaller extracts into a Directory starting with "./_temp", ie. it tries to create an install Directory at the current directory. To me it seems that it doesn't look after the environment variables. You can copy the downloaded installer into eg. c:\Temp and then start a command prompt Switch to c:\Temp and run the installer from within the command prompt window. This will extract the temporary files and run the installer in GUI mode and works flawlessly.
Hello Thanks for the recommendations. I just moved the directory installation files to TEMP and my installation is running. Emerson Brandao
