Cannot Find keycodev2.dll or invalid keycode

Have you ever come across this problem, when you have crystal report setup file. Which includes all the merge modules and license key for crystal reports. But still you are getting this error while deploying your application on the server.

Solution:

1. Install CR redistrubutalbe on designated machine(using the correct version key, had some problems with an upgrade key)
2. Deploy the application including the mergemodules:
   Crystal_Database_Access2
   003.msm (necessary if you use ado)
   Crystal_Database_Access2003_enu.msm (necessary if you use ado)
   Crystal_Managed2003.msm
   Crystal_regwiz2003.msm (don't forget to set license key in properties)
   VC_User_CRT71_RTL_X86_---.msm
   VC_User_MFC71_RTL_X86_---.msm

i have more links that are related to this topic and different version of Crystal report

Cannot Create Windows Folder Named Con

Status:
It is true that you cannot create a folder with the Following names

• PRN
• AUX
• NUL
• LPT1
• COM1
• Potential drive letter - A: to Z:
• A number of others

If you try to name a folder using one of these reserved names, the name will automatically revert to the default, generally "New Folder". Moreover, if you try to use a reserved name to name a file such as a Notepad or Microsoft Word document you will generally receive an error message similar to the following:

Microsoft MS-DOS reserves certain names for system device drivers. If you try to name a file using one of these names, you will receive the following error message:

Write Fault Error Writing Device
Abort, Retry, Ignore, Fail?

The solution is to change the file name.

Below is a list of default device driver names.

   Name    Function
  ----    --------
  CON     Keyboard and display
  PRN     System list device, usually a parallel port
  AUX     Auxiliary device, usually a serial port
  CLOCK$  System real-time clock
  NUL     Bit-bucket device
  A:-Z:   Drive letters
  COM1    First serial communications port
  LPT1    First parallel printer port
  LPT2    Second parallel printer port
  LPT3    Third parallel printer port
  COM2    Second serial communications port
  COM3    Third serial communications port
  COM4    Fourth serial communications port
    

To identify system device driver names, use one of the following two commands:

• mem /d more
• debug d 0070:0000
