Installation and Upgrade

Caché Direct is installed automatically when you install Caché. Sometimes, however, you may want to install the client-side software on a machine where Caché is not installed. This appendix describes how to do so.

Installing VisM on a New Machine

The easiest way to install VisM is to install the Caché client software as usual. You can, however, install the Caché Direct client software manually. To do so:

Make sure that you have installed the Microsoft Visual 2008 Redistributable Package, which is needed in order to register the VisM DLLs.
Copy the following files from a machine where the client is installed:
- For Caché Direct before version 5.1 32–bit systems
  - NTI.dll
  - NTIIPTCP.dll
  - Cmvism32.dll and all files with similar names
  - ISLog.dll
  - VISM.ocx
- For Caché Direct 5.1 and later 32–bit systems
  - cconnect.dll
  - Cmvism32.dll and all files with similar names
  - ISCDLink.dll
  - ISLog.dll
  - VISM.ocx
- For Caché Direct 5.1 and later 64-bit systems
  - cconnect64.dll
  - Cmvism64.dll and all files with similar names
  - ISCDLink64.dll
  - ISLog64.dll
  - VISM64.ocx
Copy the files from the directory C:\Program Files\Common Files\InterSystems\Cache and paste them into the same directory on the target machine.
Open a command prompt, navigate to this directory, and enter the following command to register the ActiveX control (must be run by a user with administrator privileges):
For 32-bit systems
```
C:\Windows\SysWOW64\regsvr32 vism.ocx
```
For 64-bit systems
```
C:\Windows\System32\regsvr32 vism64.ocx
```
