Re^7: Can't run Clustalw through Bioperl

$ENV{CLUSTALDIR} = 'C:\Program Files (x86)\ClustalW2';

Please look very carefully at the path. On my current machine, I have both /Program Files (x86)/ and just /Program Files/ directories. Almost all my Program Files are in the "plain" directory. Just one program lives in /Program Files (x86)/.

I can't say for sure whether this will help or not, but it is an anomaly that I noticed on this particular machine.

The (x86) variant is where 32 bit applications live. The "plain" directory contains 64 bit apps. It's a pretty good bet that the OP's application is 32 bit. Premature optimization is the root of all job security	[reply]

Another victim of file system redirection? If the promtp is 64bit and the perl is 64bit there is no chance to view the 32bit part of the installation. If just one component of the chain is 32bit there is no chance to view what the OS consider to be only 64bit related. If you need you can use the special path `sysnative` See mines: Re: Cannot execute external process: Win32 Win64 SysWOW64 and System32 redirection and Re: Reading subkeys from registry -- evil registry redirection?

Well the machine that I saw this on is a Win XP laptop! No 64 bit here! By definition, all apps are 32 bit. I was just wondering if there is some path mismatch between a newer version that installs to the (x86) directory and an older installation that installed into the "plain" directory. I am quite sure that you are correct about 64 bit installations on a 64 bit machine. But I am also sure that in the pre-64 bit era the same thing happened. This (x86) thing is new.	[reply]
