Frequently Asked Questions
This is a list of frequently asked questions about using mikroElektronika compilers. 
If your question is not answered on this page, please contact mikroElektronika Support Desk.
Can I use your compilers and programmer on Windows Vista (Windows 7) ?
Our compilers and programmer software are developed to work on and tested on Windows 98, Windows 2000, Windows 
ME, Windows XP (32 and 64 bit), Windows Vista (32 and 64 bit) and Windows 7 (32 and 64 bit) and they work ne on 
these operating systems. 
You can nd the latest drivers on our website.
I am getting “Access is denied” error in Vista, how to solve this problem ?
Please turn off User Account Control (UAC). This should make your software fully functional. To do this, follow the path 
in your Windows Vista (logged in as administrator) Control Panel › User Accounts › Turn User Account Control on 
or off, uncheck Use User Account Control (UAC) and click OK.
What  are  differences  between  mikroC  PRO,  mikroPascal  PRO  and  mikroBasic  PRO 
compilers ? Why do they have different prices ?
Basically, there is little differences between these compilers. mikroC PRO is standardized with ANSI C, and it is much 
more complex and it is far more difcult to write the compiler for it. We used a lot more resources for making it than what 
we used for mikroPascal and mikroBasic. We also worked on some very complex topics such as oating point, typedef, 
union, a completely new debugger and many other. Because of that there is difference in price.
Why do your PIC compilers don’t support 12F508 and some similar chips ?
Unfortunately our PIC compilers don’t support 12F508 and similar chips because these chips are designed to use 12-bit 
wide instructions. Our compiler support MCUs which use 14-bit or wider instructions.
What are limitations of demo versions of mikroElektronika’s compilers ?
The only limitation of the free demo version is that it cannot generate hex output over 2K of program words. Although it 
may sound restrictive, this margin allows you to develop practical, working applications without ever thinking of demo 
limit.  If  you  intend  to develop  really  complex  projects  in  one  of  our  compilers, you  should  consider  purchasing the 
license key.
Why do I still get demo limit error when I purchased and installed license key ?
If you are rst time installing and registering compiler, you need to follow instructions exactly as described in registration 
procedure. License is valid only for the computer from which request is made, so license requested from one computer 
won’t work on another computer. You can nd on our site manual and video describing in detail how to get your license. 
If you previously had an older version of our compiler and have working license key for it but it doesn’t work with new 
compiler, you have to repeat registration procedure from the new compiler and you will get a new license.
