MATLAB: Do I receive errors that COM servers could not be installed when installing MCRInstaller

abortingcominstallationMATLAB Compilermcrmcrinstallerregisterserversunable

I am trying to install MCRInstaller so that I can run a deployed application from MATLAB. I run MCRInstaller.exe and before the installation process is complete, a popup error dialog box appears with the following error message:

 Aborting installation - Could not register COM servers.

As a result, the installation fails and I am unable to run a deployed application.

This bug has been fixed in Release 14 Service Pack 3 (R14SP3). For previous product releases, read below for any possible workarounds:

There is a bug in MATLAB 7.0 (R14) in the way that MCRInstaller handles registration of COM servers. To work around this issue, try registering the COM servers manually by performing the following steps:

1. Open a Run dialog box by selecting Run from the Windows Start menu.

2. Open a DOS command prompt window by running the command "cmd".

3. Use the DOS command "cd" to change directories to $MCR_ROOT\v70\runtime\win32, where $MCR_ROOT is the root directory in which you tried installing MATLAB Component Runtime.

4. Execute the following commands:

 regsvr32 mwcomutil.dll

and:

 regsvr32 mwcommgr.dll

After executing each of these commands, a dialog box should appear stating that the COM server has been successfully registered. After this step, installation of MATLAB Component Runtime should be complete.

MATLAB: Is it possible to install the MCR manually without executing MCRInstaller.exe

To install the MCR without using the normal installer on versions of MATLAB prior to R2007a:

1. Build the MCRInstaller.zip using the BUILDMCR function.

Alternatively, you can use the MCRInstaller.zip that is in your $MATLABROOT\toolbox\compiler\deploy\win32 directory (where $MATLABROOT is the MATLAB installation directory, as returned by typing

matlabroot

at the MATLAB command prompt.)

2. Install the MCR by unzipping this file to the directory where you want to install the MCR. You should choose a directory outside of the MATLAB directory structure.

3. Add the directory $MCR\ver\runtime\win32 to your system path (where $MCR is the directory in which the MCR is installed and <ver> corresponds to the version of MCR that is installed).

4. If you would like the MCR to be able to handle applications with COM objects, you must also perform the following steps:

First, open a Run dialog box by selecting Run from the Windows Start menu. Then open a DOS command prompt window by running the command "cmd."

Use the DOS command "cd" to change directories to $MCR\v70\runtime\win32.

Then execute the following commands:

 regsvr32 mwcomutil.dll

and:

 regsvr32 mwcommgr.dll

Note that installing a subset of the files that are contained in MCRInstaller.zip might not allow your application to run successfully.

For newer versions of MATLAB, there is no way to install the MCR without ever using MCRInstaller.exe. However, you can install the MCR by copying an existing installation of the MCR to another computer. More information can be found in the documentation on the web at:

MATLAB: Do I receive the error “Aborting installation…” when trying to run the MCRInstaller on Windows NT

This bug has been fixed for Release 14 SP1 (R14SP1). For previous releases, please read below for any possible workarounds:

This has been verified as a bug in way that the MCRInstaller handles the installation on a Windows NT machine.

Currently, to work around this issue:

1. Ship the following file along with the MCRInstaller:

$MATLAB\toolbox\compiler\deploy\win32\unzip.exe
(where $MATLAB = the MATLAB root directory on your machine)

2. On the target Windows NT machine, run the MCRInstaller.exe.

Let it fail with the "Aborting installation..." error message.

3. After it fails, copy unzip.exe (from Step 1) to the target installation directory specified in Step 2.

4. Open a DOS command prompt and change to the target installation directory specified in Step 2. You should see the following files:

 _MCRInstaller.exe
 matlab.ico
 mcr_banner.bmp
 mcr_splash.bmp
 unzip.exe

5. Issue the following command from the DOS command prompt:

 unzip  _MCRInstaller.exe

Note that _MCRInstaller.exe and MCRInstaller.exe are two different files. MCRInstaller.exe extracts the _MCRInstaller.exe file at some point during the installation. Be sure that the unzip command is used on the _MCRInstaller.exe file in the target installation directory.

6. Add the following directory to your system path:

$MCRROOT\v70\runtime\win32

where, $MCRROOT = target installation directory specified in Step 2

For example, if you specified the following installtion directory in Step 2:

   D:\Applications\MathWorks\MATLAB Component Runtime

Then,

$MCRROOT = D:\Applications\MathWorks\MATLAB Component Runtime

And you should add the following directory to your system path:

   D:\Applications\MathWorks\MATLAB Component Runtime\v70\runtime\win32
