I have Windows7 machine available with 4870x2 graphics and it is said in the manual that Catalyst driver is not fully installed in Windows7 and needs manual extraction of three files in order to make MW work. It says in Readme file:

Note on Windows 7:

The Catalyst driver does not install the CAL libraries on Windows 7. One has to extract them from
the driver package (usually using the expand command) and put them in the Windows\system32 folder.
The needed files are (the suffix "64" applies only to 64Bit systems):

amdcalrt.dll or amdcalrt64.dll
amdcalcl.dll or amdcalcl64.dll
amdcaldd.dll or amdcaldd64.dll

I have tried expander.exe command line extraction the way Microsoft describes on their website, but it showed "unable to open Catalyst.exe" file. How can I extract those three files from the Catalyst installation package? Could somebody put exact describtion of extraction, or even extract and hang those three files online for download in a ZIP file for both 32 and 64 bits?

Just use the new Catalyst 9.3 (has official Win7 support). Then you only have to copy and rename the files as described for Cat 9.2.

Just setting up a box for a friend - and could not resist to try his 4850. :))

Well, reading about it is definetly different to seeing it... this IS fast.

I gess I got to my one too. Any recommendations? I'm not looking for the fastest, more like "best bang for the buck"

4850 X2 from saphhire here... Vista64, 9.3 driver.... 0.19e gpu client... no problems... great bang for the buck once enough GPU wus are available.

I've successfully used the latest official Catalyst 9.5 for Windows 7 64 with my HD 4870. You still need to recreate the same three missing dll files.

I don't know if it's useful to say that, but a friend tested the optimization with a Radeon HD 4890, and it works very well. 5-8 seconds by workunit.

I've successfully used the latest official Catalyst 9.5 for Windows 7 64 with my HD 4870. You still need to recreate the same three missing dll files.

Hi people,
I have a problem with the last catalyst 9.5 for Win 7 x64.
I reinstalled OS from Beta (using 8.12 and x64 ATI GPU app with no serious problems) to RC1 version.
But I can´t find any aticalX64 dll in the system after driver installation (only 3 "normal" aticalx dll in the Windows/System 32 folder). I tried make copy and renamed this dll, but all workunits with x64ATI GPU application are crashed. It works only with (the change to) 32b_ATI_SSE2e in the project directory! :/ Response of the OS is worse, than before reinstalling :( and I´m confused, because I tried new re-installing of drivers and OS without progress :(
Needs the x64 ATI GPU app the ati&amdcalrt64.dll, ati&amdcalcl64.dll and ati&amdcaldd64.dll in the Windows/System 32 folder?

(Win 7 64 bit, Q6600, 6 GB RAM, ATI 4870, cat. 9.5 for Win 7 x64)

It sounds like you installed the 32-bit version instead as installed the 64-bit version on my system and got the 64-bit .dll's

Few hours without sleep and the repeated "fresh" installation of Win 7 RC1 x64 and old catalyst 9.1 without copying and renaming dll files have been solved the "x64 GPU ATI app" problem.

Still, I have a few questions.
1. Have you (and where) in Windows System, in the case of win 7 x64 and 9.5 catalyst - aticalx64 or amdcalx64 dll files?
2. In the same case (win.,cat.), which 3 files are missing and need recreating (?copying, renaming and putting them?)?

Thanks for the answer.

ATI/AMD renamed the CAL libraries with the latest driver release. To get the GPU app running,
duplicate the following files in your Windows\system32 folder (the suffix "64" applies only to
64Bit systems):

aticalrt.dll or aticalrt64.dll
aticalcl.dll or aticalcl64.dll
aticaldd.dll or aticaldd64.dll

Now Rename the copies to

amdcalrt.dll or amdcalrt64.dll
amdcalcl.dll or amdcalcl64.dll
amdcaldd.dll or amdcaldd64.dll

arkayn: this readme text isn´t helpful to me (1 day ago), therefore 2 follow up questions for x64 Win 7 and catalyst 9.5

So triple 4870's are out of the question for now I see :)
I have an linux box with a 3870 and Ubuntu 64bit with Cat 9.1 set up when you get around to a linux app.

Ditto!

I know this thread is old but I didn't know where else to post my problem.

I don't understand how this programme works. I have a 4870 and would love to use that to help out but when I put the programme directory (win64) in the Milkyway project directory or copy the files to the project directory the files corrupt.

Can someone post a step by step guide, if possible?

Thank you very much.

What I forgot to mention is that the astronomy_0.19_ATI_x64f file always reports that the three AMD files are missing, no matter where I place them or however many times I copy them to the system32 folder.

I am running Vista64 with the 9.7 drivers. I can't downgrade to the 8.12 as the 8.12 constantly crash my PC (ATI drivers stop working).

And I don't understand what you are trying to do. You have to unzip the files in the package to the milkyway project directory.

Where does it report that? Actually you have to copy the three files and rename the copies, so you should have the three amdcal*64.dll as well as three atical*64.dll files in the system32 folder as explained in the readme. If you want to use the 32bit version with your Vista64 than you have to do the copy and rename in the SysWOW64 folder.

By the way, look at this thread!

This is the error I get . As you can see in the right window I have copied, as well as renamed the files in System32 but the programme still says it can't find the files. After reading your reply I even checked and made sure the three files were in the WoW folder as well but the problem persists.

I just tried the 19e programme and it reports the exact same problem. I will reinstall my drivers just to make sure but I do hope that a new client is made as the 8.12 drivers are eight months old.

This is the error I get [..]

I see that you don't have the files with the original names in that directory. Running Cat9.2 and up on a 64bit OS you need the three (copied and renamed) amdcal*64.dll files as well as the three original atical*64.dll files. The ones without 64 in the name are the 32bit versions (in case you have not removed the 64 while renaming them).

The original 64bit files were never named atical*64.dll, I renamed and added those three files to the directory and it still has had no effect. I've reinstalled the 9.7 drivers and it's had no effect.

As I said, I hope the GPU application is updated to include the changes made to the ATI drivers that took place over six months ago. Soon new video cards will be released which will not run on the 8.12 drivers (not without the .ini 'hack').

Until then I will just run MW on my CPU and wait.

are you installing the 64bit video drivers? I don't think the 32bit cal files should be there unless the 32bit driver was installed.

It's impossible to install 32bit drivers in a 64bit OS and visa versa, therefore I have installed 64bit drivers in Vista 64. The lack of the numbers 64 when it comes to the driver is just the way AMD's drivers work.

that's what I thought as well, just thinking aloud.
