多少情况下我们的机器上可能都已经安装了Office 2007等32位的Office，下载AccessDatabaseEngine_X64.exe安装时多半会碰到下面的错误信息，从而无法继续。

莫非我真的只有升级到Office 2010 64位版一条路可以走了么？可是貌似微软都建议我们用32位的而不是64位的，我可不想就为这一个ODBC去升级惹麻烦。下面是Microsoft关于是用Office 32还是64的回答。

Yes, 64-bit Office 2010 product upgrades will be available. However we strongly recommend most users install 32-bit version of Office 2010 on both 32 and 64-bit Operating Systems because currently many common add-ins for Office will not function in the 64-bit edition. The 64-bit installation of Microsoft Office 2010 products will be available for users who commonly use very large documents or data set and need Excel 2010 programs to access greater than 2GB of memory. There may be technical issues with the 64-bit version and in order to install a 64-bit version of Office 2010 product users must have a 64-bit supported operating system on their PC.

所以应该找个办法能在安装了32位Office的机器上安装这个64位的ODBC驱动。下面是更改方法：

先用7zip把AccessDatabaseEngine_X64.exe接压缩，里面会有一个AceRedist.msi安装文件，然后用Orca（下载地址http://www.technipages.com/wp-content/uploads/2007/11/orca.Msi）打开这个MSI，找到LaunchCondition里面的BLOCKINSTALLATION，删掉，保存。现在在运行AceRedist.msi，哈哈，非常顺利。经过我的测试，使用上也完全没问题。
