IN_Style Macros required

What are IN_Sys, IN_Styles, IN_Macros?

Are those something your client should be providing? If so, you will need to consult with your client about them.
Are they something your company has set up? If so, you will need to consult with your company to make sure your software is set up correctly.

Has this project been working fine, and these are new error messages?
Is this a project your coworkers have been working on that won't work on your computer?
Is this a brand new project?

You should definitely talk to whomever at your company set your computer up. Whether these are system file, company files, or client files, they should provide you with what you need to do your job.

I recommend telling everyone in the title of your post (every post!) that you are working with MX SS4.

HI,

Thanks for reply. I had worked on this project two years before on mx SS4.Since then i had shifted to openroads and unistalled SS4. I needed to modify it for some reason.So i reinsitalled MXSS4.Now this messsage crops up wheni try to open the file

Who is the client? Perhaps someone else here has done work for them, and can help you out with the files. It's possible that your initial installation had client files installed on top of the software, and uninstalling wiped it all out.

You may be able to contact the client and ask them for their MX standard files, if that's what these are.
Nothing worse than a zombie project - one that you thought was finished, but rises from the files years down the line...I'm afraid I can't help more (I don't use MX at all) but I wish you luck.

Have you installed the correct edition of MX SS4? Based on the folder name I suspect those are Indian Country Kit files. They most likely only exist in the specific Indian version of MX SS4.
If you recently downloaded MX it will probably be MX SS10, and as far as I know there is only an English (GB) Country Kit version available.

Maybe someone still has this edition of MX installed and can provide you the files.

Yes jane that was precisely the issue.I fortunatly had the setup of earlier versions and somehow managed to get the styles.The problem was resolved.
