MATLAB: Do I get a message “Unwritable Folder” when installing the R2007a prerelease

MATLAB

I downloaded and ran the installer for the R2007a prerelease. After authenticating as an administrator and selecting the default installation location, I get an "Unwritable Folder" error saying that the directory is read-only.

This bug has been fixed in Release 2007b (R2007b). For previous product releases, read below for any possible workarounds:

This is an known issue with the R2007a prerelease. As a workaround, manually create the MATLAB74 folder within /Applications.

The reason that you are receiving this error could be due to the fact that the DLL needs to be registered manually on the deployment machine using the regsvr32 command from the system command prompt.

For example:

regsvr32 myExcelDLL.dll

You must also register mwcomutil.dll and mwcommgr.dll for each version of MATLAB or MATLAB Compiler Runtime (MCR) you are using.

After registering the components, restart the machine and retry running the batch file.

If you still receive the same error, the issue could be with vcredist(86) not being installed properly.

Run the dependency walker tool on the executable and check if it throws any warning related to ATL80.dll. If it does, then perform the following steps to rectify the issue:

1) Install vcredist from MATLAB Compiler Runtime (MCR) at:

$MCRROOT\$version\bin\win32\vcredist_x86.exe

where $MCRROOT is the installation folder of the MATLAB Compiler Runtime and $version is the MCR version (for example, v74 for MATLAB Compiler 4.4 (R2006a)).

2) Try running regsvr32r again. If it still fails, download the following update from Microsoft:

MATLAB: Do I receive a warning message when I use a Simulink object as the variable name in a mask within a library in Simulink 6.4(R2006a+)

This bug has been fixed in Release 2007b (R2007b). For previous product releases, read below for any possible workarounds:

'Type' is a Simulink object type (read only) parameter and its value is 'block'. Since 'Type' is a reserved name in Simulink, it has been set to read-only.

As a workaround, change all instances of the variable 'type' to 'type1' or any other name within the library. In this case, make changes in the Mask Editor- Parameters pane as well as the S-function parameters list.
