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

[John Joseph]

Thanks so much, Jayesh.  It's working now!
 
My mistake is that I had thought I was working as an administrator, but wasn't really.  Your simple instruction to right click on the command prompt icon and click "Run as administrator" helped me get MPICH2 properly installed.  Next, I had to right click on the R icon on my desktop to "Run as administrator" in order to install an Rmpi package from special zip file.  And, now, in R, Rmpi is ....finally....really installed and seems to be doing everything it should.
 
Now, I did all this by following the complete instructions (from where to get MPICH2 to testing its installation in R with R commands) that are at the website I mention in my previous e-mail.  So, I really didn't give your instructions a thorough testing...Well, I did try all three of the steps you listed, and got no errors when I typed "msiexec / i mpich2-1.3.1-win-ia32.msi" (note that I needed a space between the "/" and the "i"), but then couldn't get it to go in R, but I might have had the path variable still improperly defined from a previous attempt, even though I had unistalled MPICH2.
 
Well, anyway, thanks so much for your help.  I really appreciate it.
 
John Joseph

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.
