文件不以'％PDF-'开头 [英] File Does Not Begin With '%PDF-'

问题描述

昨天我有一个特殊的问题。客户将我的一个Delphi应用程序放在一些东芝笔记本电脑上，一切都很好，直到生成一些Acrobat文件作为Rave 7报告，产生了主题错误。

I had a peculiar problem yesterday. A customer put one of my Delphi apps on some Toshiba laptops, and all was fine until it was time to generate some Acrobat files as a Rave 7 report, which produced the subject error.

笔记本电脑的Acrobat 7 Standard安装了XP SP3和IE8。我卸载了Acrobat 7 Standard，放入他们躺着的Acrobat 5 Reader，问题就消失了。但是，客户没有看到回溯Acrobat作为解决方案，因为这个Delphi应用程序在XP SP3，IE 7和Acrobat 7 Standard中运行的通常环境不会显示此问题。

The laptops had Acrobat 7 Standard installed with XP SP3 and IE8. I uninstalled Acrobat 7 Standard, put in Acrobat 5 Reader which they had lying around, and the problem went away. However, the customer doesn't see backtracking Acrobat as a solution, because the usual environment this Delphi app runs in of XP SP3, IE 7, and Acrobat 7 Standard doesn't show this problem.

Google搜索未发现任何近期原因或影响。 Microsoft和Adobe KB否认存在任何问题。

A Google search didn't reveal any recent causes or effects. The Microsoft and Adobe KBs deny that any problem exists.

有关具体区域需要解决方法的任何线索？今天我要卸载IE8并重新安装IE7。

Any clues as to what specific area needs a workaround? Today I'm going to uninstall IE8 and reinstall IE7.

推荐答案

我遇到了同样的问题，在IE中用Adobe ActiveX插件。这是一段时间以前，但如果我没记错，问题是某些版本的Acrobat 7中的ActiveX，可能与PDF本身的特定版本相结合。安装最新的Adobe Reader解决了这个问题。

I came a cross the same problem, in IE with the Adobe ActiveX plug-in. It was some time ago, but if I remember correctly the problem was the ActiveX in some versions of Acrobat 7, maybe combined with specific versions of the PDF itself. Installing the latest Adobe Reader solved the problem.
