I have installed WampServer 2.1 and it is mostly working well. Thanks a lot.
However, I do have a major problem: I need PEAR, so I can install certain packages such as the Excel Spreadsheet Writer.
All prior documentation is apparently referring to PHP 5.2 when a go-pear.bat existed. But there is evidently no such thing in PHP 5.3 or WampServer 2.1 How do I install PEAR and PEAR packages in 2.1 ?
