Windows 7: Finding CLSID of scripting language "PerlScript"

I'm running MUSH 4.43 on a 64-bit windows 7 install.
I'm trying to start scripting in Perl(Perl because I'm really familiar with the language), but I'm hitting this error:



which is telling me that MUSH has not been able to find the perl installation that I have (ActivePerl 5.12):



After searching these forums and the web I expected to be able to click the register DLL button in the scripting window, but it's greyed out for perlscript.
I've tried copying perl512.ddl to different places, but I'm just not having any luck.
Any suggestions?
Thanks,
Renrav

Sounds like the script engine is not installed. Running Perl from the command line doesn't use the script engine.

Try finding it here:

You want "Active Perl" or the script interface, whatever they call it exactly.

I see the most important thing not mentioned...

Install the 32-bit version of the Perl libraries. No harm in installing the 64-bit ones, but you definitely need the entire doodah in 32-bit for it to work with MUSHclient, since MUSHclient is 32-bit itself, and it is impossible to communicate with a 64-bit Perl for more reasons than I can count. Make sure that _everything_ that needs to be done to get it working properly is done in a _32-bit_ context (there is such a thing as a 32-bit and a 64-bit explorer if you have 64-bit windows), as Windows has a fair bit of hocus pocus going on to hide the differences from users.

I ran into this issue when trying to get Python working on my new 64-bit installation of Windows. Combined with the fact the latter had a bit broken WSH scripting interfaces in newer versions, it took me a while to find the issue.

(Of course, I'm probably going to get laughed at and told there's no such thing as a 64-bit Perl package, but I don't know anything about Perl, so just throwing it up in case there might be one.)

?

It was late, and I was too lazy to check if there was such a thing as a 64-bit package. For all I knew, I wrote that and it didn't exist. =)

No, I mean, that line was in the original post.

Oh, oops. Well, I didn't see that either! =)

Awesome! That was my issue, I had installed the 64-bit version of activeperl. I installed the 32-bit and it now works. Now I just need to start digging into the code.
Thanks Everyone!

Thanks for clearing that up Worstje! I have amended the topic headers for Perl and Python to mention that you should get the 32-bit versions.

I'm having a real hard time finding the 32-bit active pearl. I've found 86 and 64 bit but I can't seem to find 32 bit. Would anyone happen to have a link?

The x86 version is the 32-bit one (it refers to the old 8086 processor). See:

http://en.wikipedia.org/wiki/X86

I created a world called test and switched to perlscript and got this:

Which file did you download and install? This one?

http://downloads.activestate.com/ActivePerl/releases/5.12.2.1202/ActivePerl-5.12.2.1202-MSWin32-x86-293621.msi

Yep. That's the one.

Well I tried to reproduce this on a spare PC.

I downloaded and installed MUSHclient v4.63:

http://www.gammon.com.au/forum/?id=10640

I then made a new world and tried to switch to Perlscript and got the error message you mentioned.

I then downloaded the Perl installer and ran that. 22.6 Mb lol compared to 3.1 Mb for MUSHclient. Oh well.

About 10 minutes later, when the Perl installer finished, I re-opened MUSHclient, and switched to Perl. No error message, and a test of Perl worked.

This was under Windows XP, I don't know what version of MUSHclient you are using or what operating system, but it ought to work. Maybe uninstall any earlier versions of Perl in case you had the 64-bit one already there.

Perl installer?

I use windows 7 by the way

The file we were discussing:


http://downloads.activestate.com/ActivePerl/releases/5.12.2.1202/ActivePerl-5.12.2.1202-MSWin32-x86-293621.msi


That installs Perl.

And it works!. Thanks for all the help! Sorry if I seemed a bit clueless, it's getting ab it late here.

i am trying to set up the client on an xp machine, without administrator privileges.

activeperl runs well enough using the perl binary, but registry has been locked for modification.

is there a way to tell the client where the perl binary and it's libraries are located without using the script interface?

tia.

Nope. Mushclient relies (mostly) on the Windows ActiveScript interface, and needs the scripting engines to have registered itself.

For a scripting language that does not need the registry, there's Lua.

It's not the binary and library you need, it's the DLL which supports the scripting, and the registry entry for that DLL needs to be made. So if you can't change the Registry you are out of luck.

As WillFa says, Lua is supplied with MUSHclient and does not rely on the Registry.

wow. thanks for the superfast reply. will give lua a try.
thanks for the info.
