[mpich-discuss] openSCManger fails in Windows 7 Home Premium

[Jayesh Krishna]

Hi,
 I would recommend installing MPICH2 from an administrator command prompt. Please follow the steps below,

# Uninstall any existing versions of MPICH2 in your machine
# Right-click on the command prompt icon and select "Run as administrator" . This opens an admin command prompt
# Install MPICH2 using msiexec utility from the admin command prompt (Type "msiexec /i mpich2-1.3.1-win-ia32.msi" from the admin command prompt)

 Let us know if it works for you.

(PS: Note that opening a command prompt from an administrator account does not provide elevated/admin privileges.)
Regards,
Jayesh

Hello.
 
I'm trying to use MPICH2 to install and run the R package Rmpi on a Windows 7 Home Premium (64-bit) OS, on an Intel Core i7 desktop computer.
 
I use R on this computer with no problem.  It's 32-bit, and installed in C:\Program Files (x86).  
 
I followed instructions posted at http://www.stats.uwo.ca/faculty/yu/Rmpi/windows.htm.  In particular, I did the following:
 
1.) I downloaded the 32-bit version of MPICH2 1.3, and followed the installation wizard prompts. 
 
2) In the "Advanced System Settings" I edited the variable PATH value by adding ";C:\Program Files (x86)\MPICH2\bin" to the value.  
 
3) I launched wmpiconfig.exe from the Start menu, gave my administrator account name and password, clicked "Register" then "OK".  When the Configurable Settings dialog box appeared I clicked "Get Settings".  At this point I should get a green color on the left hosts panel, but I don't, so I am then supposed to (according to the above website instructions) type at the command prompt while logged on as the administrator the following: smpd -install -phrase behappy.  ("behappy" is simply a passphrase).  But I get this message:
 
 OpenSCManager failed:
"Access is denied. <error 5>
Unable to remove the previous installation, install failed.
 
The part "Unable to remove the previous installation" makes me suspect that a previous attempt I had made a mistake on had left some files that needed to be removed before I could try again.  So, I did a "system restore" to a point before I had ever tried to install MPICH2.  Then I repeated the above steps.  But I still got exactly the same message.
 
I've read a posting for another person who had credential problems with Windows 7 Pro Edition, rather than Windows 7 Home Premium, but I couldn't see how I could apply it to my case.  Also, chapter 9 of the Installation Guide doesn't cover this situation directly, as far as I can tell.
 
Any ideas would be much appreciated.
