Hello,

I installed Ansys 2020.1.  i'm getting an error message when I start ChemKin.  Error message says can not find ckjni.dll on the computer.

I verified that the file is there.  I even reinstalled Ansys.

Please help. 

Thank you

Could you please share the screenshot using the 'Insert Image' option? Ansys employees cannot download attachments on this website.

Thanks.

Hello Karthik,

 

Here is the image again.

 

[tsiriaks]

Open CMD Prompt and enter the following commands

set PATH=C:WINDOWSsystem32;C:WINDOWS;C:WINDOWSSystem32Wbem

"C:Program FilesANSYS Incv201reactionchemkinpro.win64binrun_Chemkin.bat" Pro

does this work ?

If not, enter the command

set

and post the output of it here.

Also, do you have an install.err file under C:Program FilesANSYS Inc   ?

Thanks,

Win

[lyip6]

tsiriaks,

 

Thank you for your response.  Unfortunately, that did not work. Here are the files

 

 

 

[tsiriaks]

Could you post the file content inline ? ANSYS employees are not allowed to download attachment

Thank you.

[lyip6]

tsiriaks,

 

The file is long so I took screenshots of it.  

[tsiriaks]

I've never seen most of these Chemkin/Reaction related environment variables. Did you or your IT manually create them ?

I think we should try to remove them but you may want to back it up first.

Please also post the content of your install.err file

[lyip6]

tsiriaks,

 

Here is the content of install.err

We didn't add those environment variables for Chemkin/Reaction.

I'll try to remove them.

 

[lyip6]

Which variable do you want me to delete?

[tsiriaks]

Basically everything that has the term 'chemkin' or 'reaction' whether in the name or value, just remove them.

What was the installation package name that you used to install Chemkin ? My machine doesn't have any of these set and it can be launched fine.

[lyip6]

I used the Ansys 2021 R1 installation media to install this.

[tsiriaks]

The ISO images ? what's the exact file name ?

[lyip6]

it is setup.exe

 

 

[lyip6]

tsiriaks,

 

I installed the Ansys suite and a clean computer.  It is working.  However, on this particular computer it is not working.  I even tried to reinstall Ansys 2020 R1 Suite.

 

Thank you for your help

[tsiriaks]

Can you check/post the environment variables of another machine that's working ?

[lyip6]

tsiriaks,

Here is the environment variables from the working computer.

 

[tsiriaks]

ok, as you see here, there is no environment variables for Chemkin or Reaction set. There might be something wrong during the installation on that machine and somehow the environment variables that were set only in the install wrapper were passed to be permanently set on the machine. Maybe, it's best you uninstall (using the uninstall.exe with 'run as admin') , check if there is any remaining environment variables and delete them. Then, reinstall again with 'run as admin'

[lyip6]

tsiriaks,

I reinstalled Ansys but it is still not working.  The environment variables is clean now.

 

[tsiriaks]

Hmm, Can you post the current environment variables on this machine ?

Is there anything new in the install.err file ?

[lyip6]

tsiriaks,

 

Here is the current environment variables after the reinstall.

 

Here is the install.err log

Does it still show the same error message ? If so, what is the output of the following command

dir /s "C:*ckjni.dll*"

[lyip6]

It is still not working.  Here is the results of the command.

[tsiriaks]

Hmm. This is fine.

Can you post the screenshot of the error message again but make sure you expand the window so the entire error message can be seen ? Or if you can copy the text content of the error message and post it here, that would be good too.

I've asked around about this and there are some thoughts

1. Chemkin is a java app ... Is Java installed on the computer and in the user's path? You can use the following command 

set | findstr -i java

and post the output of it here.

 

2. Chemkin may be having trouble creating its environment, which could result in .dlls not being located. Please use the following command

"C:Program FilesANSYS Incv201reactionchemkinpro.win64binrun_chemkinpro_env_setup.bat" > C:Tempchemkin_env.txt

and post the content of C:Tempchemkin_env.txt 

 

 

[lyip6]

1) The Set | findstr -i java command doesn't return anything.

2) here is the results from run_chemkinpro_env_setup.bat

The machine doesn't have Java installed. 

Can you install Oracle Java and make sure your Path environment variable has this in there

C:ProgramDataOracleJavajavapath

Does this make a difference ?

[lyip6]

I installed oracle java it is still not working.  I see C:Programdataoraclejavajavapath in %Path% now, but it is still not working.

 

[tsiriaks]

Can you try moving this entry 

C:Programdataoraclejavajavapath

to be the first value of Path environment variable ?

[lyip6]

I moved it to the top.  still no good.

[tsiriaks]

I've consulted with developers. nHere are their comments and questionsnnThere can be incompatibility between some system dll on the machine and jni.dll in our install. nSome questions to ask the user are:n1) does the user have correct permissions to read/execute ckjni.dlln2) Is there a virus or malware software blocking execution?nnLet us know.n

[lyip6]

Hello tsiriaks,nIt has been awhile since I provided an update. I was trying to update this thread but your site was under maintenance so I couldn't update it. So I found out that this started after I installed Aspen 11. Then I reinstalled everything from scratch with Ansys 2019 R1 and Aspen 11. I didn't get the problem with Chemkin. At this point, we decided to keep using Ansys 2019 R1. nThank youn

[tsiriaks]

Hi lyip6,nThank you very much for the update. That's great find !nAspen 11 might have put some DLL's or files under Windows systems files directory, which inadvertently makes Chemkin use that same file and result in issue because it's not compatible.nIn any case, I'm glad it's working with 2019 R1. I will report back to developers in case they can check Aspen to see what causes the issue.nThank you.n

[braddonegan]

Hi Array ,nThank you for this post as it helped us troubleshoot this issue. We have a setup which requires both ANSYS 2020 R1 and Aspen Plus 11 to be installed.nRemoving or renaming the specific DLL, C:\Windows\System32\svml_dispmd.dll, fixed this problem for us. This DLL is not needed in how we use Aspen Plus.nWe had a similar problem with Fluent several months ago and had to use a similar fix but with a different DLL.nProbably not possible, but it would be great to have an option that tells the ANSYS apps to ignore external libraries.nThanks!n
