I was perplexed by a message that acro.sty was missing, since I copied both of my root directories (2 localtexmf's) from one computer to another. The acro package does not show up in the MiKTeX package manager. I recall installing it as a newbie in a haze of trial and error, but I was convinced that everything would be in the two roots.

After grepping the log file, I found that there were acro package files distributed throughout the subtrees rooted at c:\Users\Bob\AppData\{Local,Roaming}\MiKTeX\2.9, which are not my two roots. In MiKTeX settings, I found that these paths show up as roots when I check off the box to show MiKTeX maintained roots. I'm not sure what MiKTeX does in maintaining its own roots. The Roaming and Local paths are described as UserInstall and UserData, respectively. But I thought that was the point of my two roots, which is not maintained by MiKTeX.

Since the roots in the AppData paths are maintained by MiKTeX, should I be avoiding the blythe practice of blindly copying these folder trees from one system to another? I don't want to be messing around with parts of the file system that MiKTeX doesn't expect me to mess with. I fear corrupting something, or having my installations clobbered.

At present, the files in the old computer are located at


In the new computer, it seems safest to put them in one of my roots at


There are additional files that are not part of the package zip file.


In the new computer, it seems to make sense to put the html file in


At the moment, I suspect that the tpm file is autogenerated by MiKTeX when file name database FNDB and format files are refreshed/updated via the MiKTeX settings tool.


Interesting error the first time I refresh the FNDB (and only the 1st time)...

    acro is part of MiKTeX. Why did you install it manually? You should install it via MiKTeX's package manager if necessary. – clemens Sep 11 '14 at 13:56
