# Re: Errors when run zookeeper in windows ?

I suspect it has to do with the classpath - specifically having spaces in the directory name. Notice that one of the lines you included starts "Files\Java\" - that probably should be "...\Program Files\Java\..." and the space is causing problems.
```
```
Try using David's dos specific file, or edit the start script (bin/zk*.sh) to put quotes around the classpath, like in zkServer.sh

```
-cp \$CLASSPATH \$JVMFLAGS \$ZOOMAIN \$ZOOCFG &

change to

-cp "\$CLASSPATH" \$JVMFLAGS \$ZOOMAIN \$ZOOCFG &

```
and see if that helps (you might have to play with it a bit, but I suspect this will work).
```
zkEnv.sh you may need to put quotes as well:
CLASSPATH="\$ZOOCFGDIR:\$CLASSPATH"

the command to start HBase is the same as in the get started:
bin/zkServer.sh start

The following is the whole message:

```you are using java 1.6 right? more detail on the class not found would be
useful (is that missing or just not included in your email?) Also the
command line you're using to start the app would be interesting.

```Hi Zhang,
Are you using cygwin?
