Need advice: to upgrade Pic development soft and hardware for 64 bits WIN7 Pro

[hardcore]

Hi,
I'm running Win7-64bit....
Compiler: PBP2.60
Assembler: MPASM (must use MPASM with 64 bit version of Windows)
IDE: MicroCodeStudio Pro
Programmer(s): PICKit3, MikroElektronika PICFlash, MikroElektronika mikroPROG suite and (MCSP Bootloader). I have a PICstart+ as well but haven't tried it on the Win7 machine yet.
Development boards: MikroElektronika EasyPIC4, PICPLC16 and an 18F4520 board from SURE Electronics.

It was a little tricky getting the online update for MCSP working and several applications must be run with administrator rights (no big deal) but it all works nicely.

As for simulator I've never used one but I keep hearing good things about Protues VSM - don't know if it runs on Win7 though but I'd be surprised if it didn't.

/Henrik.

Thank you very much for advice.
As you said: MicroCodeStudio Plus and compiler PBP 2.50B installed OK.
Try to find MPASM:Found MPASMWIN from electronics-DIY.com
and MPASMWIN5.20 from melab.com.
From info that I found on internet MPASMWIN version more then 5. has compatibility
problem.To avoid mistake by instaliing wrong MPASM I would you like to ask you
what version of MPASM you are using and where you got it and how to update.
